I will attend the first perfomance of Company on 7th, April.
As a tourist, I don't know if I could dress casual in that perfomance.
Can you help me?
It's up to you. Certainly no code for this concert. If you feel comfortable wearing street clothes to an event where a lot of people will be dressed up-go for it!

As it's the first night, you may find a few people in real formal attire.
In November, when I was in Paris, I attended a performance at the Paris Opera (Palais Garnier), I wore a corduroy sports jacket and a tie. (I chose that because corduroy doesn't wrinkle in a suitcase.) Although the performance was a very dressy affair, I didn't feel out-of-place.
Use your own judgement.
