I just got back from Apache on a Wednesday night, it was open mic night. Any artist could sing any song, mostly older soul covers (e.g. Teddy Pendagrass, Jodeci, Al Jarreau), to the incredible band. Some artists were good, others bad but the band was incredible. I'd rather just listen to the band get funky than have to take a chance with the next singer.
Pros: Neosoul Favorite, Relaxed Atmosphere, Great Band
Cons: Sometime Bad Artists, Little to No Seating
