Night+Day

Noise Annoys When bands with names like Grotus and Neurosis get together to play, it's a safe bet the sounds that result will be pretty loud, and not very pretty. If cacophonous, hypermetal songs about mankind's imminent destruction made by white boys with goatees are your bag, a better double bill than this would be hard to come by. Dig up your industrial-strength black clothes (and your earplugs); the gloom and doom begins at 8 p.m. at the Trocadero, 520 Fourth St, S.F. Tickets are $10; call 995-4600.
