What are some of the pre-Oklahoma! groundbreaking musicals? Show Boat and Pal Joey instantly come to mind, but would like some ideas on other shows that would be considered groundbreaking.
		     			Of the Gershwin shows, Girl Crazy (1930), Of Thee I Sing (1931) and of course Porgy and Bess (1935) are classics. 
 
Cole Porter's Anything Goes (1934) is proving all over again how enduring that score is. 
 
Rogers and Hart's On Your Toes (1936), Babes in Arms (1937) and The Boys from Syracuse (193 are each imperfect shows chock full of treasures.
 are each imperfect shows chock full of treasures. 
 
Mark Blitzstein's The Cradle Will Rock (193 is dazzling.
 is dazzling. 
 
And best of all is Kurt Weill and Ira Gershwin's Lady in the Dark (1940), a true masterpiece that deserves a Broadway revival to match the brilliant National Theater production back in 1997.

		     			I'd def add Pal Joey--flaws and all--to the list.   
 
I've always wondered why Kern/Hammerstein didn't do anything as ambitious as Show Boat--and I shamefully admit I know their later shows only from the songs that became hits.

As a non- American example, one could possibly add The Threepenny Opera. I suppose Rise and Fall of the City of Mahagonny is still classed an opera, rather than a musical play?
		     			But Porgy and Bess was conceived of as and is an opera.  As is Mahagonny.   
   
And as to The Cradle Will Rock, have you seen it lately?  I have, in a pretty decent production in LA.  It came off as sub-Brecht/Weill, all message and no drama.  Groundbeaking?  Not so sure.

Definitely Lady in the Dark. I think the reason that it hasn't been done all that often is because of lingering memories of Gertrude Lawrence who apparently gave one of the performances of a life in that one. I know, that shouldn't deter someone in 2011 from taking a stab at it. Maybe Sutton Foster?
It's also an incredibly expensive show to do and not many theatregoers today know it. You would need someone with greater star power than Foster to do it. Meryl Streep about 15 years ago would've been perfect. Maybe Kate Winslet now? Or even (despite how much I hated her in ALNM) Catherine Zeta Jones.
		     			I'll vote for Lady In The Dark as well - it could be a good vehicle for several gals - Donna Murphy, Ann Hathaway (perhaps a few years too young), Foster (although she's not the most nuanced actor). 
 
Citing Anything Goes, although it was a huge hit, is a bit deceptive, because none of us has probably ever seen it with its original book, score, or orchestrations.

		     			I am trying not to sound snarky here, as someone who loathes Anything Goes - what made it groundbreaking? I do like some of the numbers, but Ethel Merman, Patti Lupone and Elaine Paige leave me cold -am I just the wrong audience? 
 
I ask this sincerely, and don't want want to appear negative.

		     			Anything Goes was anything but groundbreaking.  It was pure formula - a negligible book designed to showcase the songs and the stars.  William Gaxton (Billy) and Victor Moore (Moonface) were already a well-known team from OF THEE I SING, and Merman had just beome a star in GIRL CRAZY. 
 
In fact, the show originally had a totally diferent plot, involving a shipwreck, which had to be scrapped mid-rehearsal period when a real shipwreck occurred.  They hastily came up with the new plot.  
		     				
		     					
		     			I think some of you are just listing good musicals and not necessarily ground-breaking ones. 
 
You can start with The Black Crook. 
 
But the biggest ground-breaking musical, pre-Oklahoma!, was on film. It's "The Wizard of Oz," which does everything that Oklahoma! is given credit for doing on the stage. 
 
All the songs, dances, and musical sequences either advance plot or develop characters or both.
		     						     						
		     			Fair enough. "Groundbreaking" sets the bar higher than a Babes in Arms or even an Anything Goes qualifies far. 
 
Of Thee I Sing was the first full on political satire on the musical stage. It's also the first to win a Pulitzer for best play (though the award interestingly neglects to credit composer George Gershwin along with Ira and the book writers). 
 
I would say that The Cradle Will Rock can still be considered groundbreaking for Blitzstein's   reliance on art-songs and non-commercial song structures throughout its score, despite the creaky pseudo-Brechtian dramaturgy of its libretto. 
 
On Your Toes is generally credited as the first musical to feature a ballet as absolutely integral to the plot. Ballanchine's "Slaughter on Tenth Avenue" ballet is in fact a key plot point although in no way a psychological study of the play's characters like the dream ballets of Agnes de Mille that came along in the 40's. 
 
Lady in the Dark made psychological study of the main character it's entire raison d'etre, turning Liza Elliott's dreams each into a mini-opera. It also broke new ground in creating fantastically unpredictable scene-songs that morphed from song to song, rather than the hit-parade presentations of Porter or Rogers and Hart. 
 
And of course Pal Joey is credited as the first musical to make an unlikeable anti-hero the male lead, not to mention the depiction of one of the first truly adult relationships on the musical stage between Joey and Vera. For a show to be so loved and loathed in equal measure when it first premiered is maybe the true marker of "groundbreaking".
		     				
		     					
		     			The major "ground-breakers" of the early years of this century are operettas: THE DESERT SONG, THE STUDENT PRINCE, THE MERRY WIDOW, and others laid the ground work for serious romantic musical drams (like SHOW BOAT.)  No one really picked up on SHOW BOAT's innovations until OKLAHOMA! came along in 1943.  
 
OF THEE I SING is a clever political satire in the style of  Gilbert and Sullivan operettas that is well worth getting to know. ON YOUR TOES does not have the most cohesive book but it did introduce serious ballet as part of Broadway musical, and the score if full of endless delights.  Also try THE BOYS FROM SYRACUSE as an early example of adapting a Shakespeare play for a Broadway musical. 
		     						     						
Cast albums are NOT "soundtracks."     
Live theatre does not use a "soundtrack." If it did, it wouldn't be live theatre! 
  
I host a weekly one-hour radio program featuring  cast album selections as well as songs by cabaret, jazz and theatre artists. The program, FRONT ROW CENTRE is heard Sundays 9 to 10 am and also Saturdays from 8 to 9 am (eastern times) on www.proudfm.com

Great point, and you know what film did it even before (though arguably less well)?  The movie that inspired MGM to make Oz, Disney's Snow White.  It used to, as an obnoxious kid, drive me crazy that musical theatre books never pointed out that that was a film where the songs were largely built around story and character.  
  
Where does Love life fit in this list?  Was it groundbreaking?  I just want to hear a recording of it....

Sorry, Ericmontreal, but Love Life was from 1948, 5 years post-Oklahoma. Never saw it myself, but hearing a few of the songs didn't make me curious to hear the rest of the Lerner/Weill score.
Do the Gilbert and Sullivan operettas count? Their work had a huge impact on the evolution of musical theatre.

No, I realize it was later, but it is often mentioned as the first concept musical.
		     			Eric, Yeah, but concept musicals can also be traced back at least as far as the 30's when reviews like As Thousands Cheer presented plotless evenings of scenes and songs wrapped around one theme (like the daily newspaper headlines). Some amazing Berlin songs came out of that one show. And the long tradition of Minstrelshow to Vaudeville to Burlesque to Topical Review are all antecedents to the concept musical we have today. 
 
Some would refer to the Brecht/Weill collaborations from Threepenny Opera (192 on as concept musicals that relied on character and theme to drive the show beyond anything we today would call a recognizable plot. There's a long and glorious tradition for this kind of show that completely sidesteps the Operetta/ Melodrama side of the Musical Theater Family Tree.

		     			Then why didn't you suggest them?

Look no further than Porgy and Bess. Richard Rodgers was so enamored of Porgy and Bess, and so jealous of it, that musical theater was changed forever, not overnight, but forever nonetheless.
