Club a little outside of the city centre (but still in walking distance). Lots of punk/hardcore/indie-shows. No alcohol (or just beer maybe) allowed inside.
you can hear some great music in KSET,
like dubstep, hip/glitch-hop, rave(retro), electro, dnb, generally less mainstream music. in last 3 years you could hear autechre, edmx, luke vibert and few other awesome electronica artists..
