i will be in europe for about 4 months this summer and i’m wondering if anyone can suggest any smaller places (clubs/bars/concert venues) where i can hear some:

• death metal/black metal/grindcore/doom
• punk/ska/hardcore
• idm/drum’n‘bass/techno/breaks/hardcore/trip-hop
• noise/ambient/power electronics/experimental

basically, i’m not interested in any places that won’t allow me in based on the way i look (wrong shoes/no shorts/whatever), since those are not the kind of places i enjoy in the first place, and i’m not planning on bring any "dressier" clothes. for example, here in chicago, i can see 5 excellent punk bands at some dumpy little bowling alley for 5 bux. or, since drum’n‘bass is not very popular here, we have dnb nights at clubs on certain nights (usually midweek). so that’s the kind of info i’m looking for basically anywhere in europe since i’m going to hit most major cities (though i’m especially interested in such info in spain, italy, and greece).
