My usual raps-and-beats-and-stuff night is on at Sticky Mike's, on Middle Street, from 9ish.
Woodpecker Wooliams and Anthony of Power Lunches / God Don't Like It and that on guest set duties.
Also, downstairs from 11pm there's a free gig with good bands and more DJs. So you can flit between floors.
FREE. FREE. FREE. BOOZE. RECORDS. BANDS. FREE. FREE.
