I've experienced this place from every possible angle you can think of. (Patron, performer, engineer, producer etc) If it weren't for the crippling cost, I would do all my recording projects here.
The staff (if you need them) are excellent and know the place inside and out.
The sound is excellent. The space was designed as a studio with the provision for optional "meat-baffles" (audience members). It has a smooth and clear natural reverberation and with the draperies to cover nearly every hard surface, you can have as much or as little as you want.
As a performer it's a great place to work. However the backstage starts to get a little cramped if your band/ensemble/contraption has more than 12 people.
