In Lausanne you also have the Docks for underground/alternative music stuff, and the Backstage for a heavy metal pub.
Dunno if I'll be free on friday, but if you're planning on going to the Pickwick pub in Geneva for some pub food after work, I would be up for that!
PM me if interested in meeting up
Both MAD Club and D-Club in Lausanne are cool. Saw Luciano and Sneak friday just gone in MAD, it was pretty busy and going off in there! Sven Vaths there in a few weeks too You should check out their site, I can't think of the link but its there somewhere, just google it. D-Club last week was one of the best crowds I've seen this year, and thats alot considering I was in Ibiza for 4 months! Its abit smaller than MAD and a little rundown but it works.
Weetamix is the only underground answer for Genéve, not as big or frequent, but the lineups are cool, although I've yet to see it (this Friday coming will be my first)
