Go see if you can visit the place. Prices are listed on their website. When I checked back when I was in a band considering booking time there, it was like $700 per session with Albini, and $500 with Greg, or an intern.
He also has recorded a lot of Jazz and R&B albums (Chicago studio), I'm just not as familiar with them. He doesn't exclusively work with any particular genre, he keeps his fees very low and will work with anyone.
