THE FATHER, THE DANCE OF DEATH, EASTER, MISS JULIE by Strindberg (WHY does no one do Strindberg??)
THREE SISTERS, THE CHERRY ORCHARD, UNCLE VANYA, Chekhov
For Ibsen, I think his best is THE MASTER BUILDER...its actually better read than watching it.
Some ones you might have overlooked:
ALL OVER by Albee
ROAD by Jim Cartwright
THE MISANTHROPE, Moliere
ECCENTRICITIES OF A NIGHTINGALE by Tennessee Williams
BURIED CHILD and CURSE OF THE STARVING CLASS by Sam Shepard
THE DESIGNATED MOURNER by Wallace Shawn
A VIEW FROM THE BRIDGE by Arthur Miller
SPRING AWAKENING and LULU by Frank Wedekind
Nicky Silver and Christopher Durang are also good fun to read.
"Impossible is just a big word thrown around by small men who find it easier to live in the world they've been given than to explore the power they have to change it. Impossible is not a fact. It's an opinion. Impossible is not a declaration. It's a dare. Impossible is potential. Impossible is temporary. Impossible is nothing.”
~ Muhammad Ali
