I am trying to find out where I could go to listen live music (guitar, drums, etc.) I am not considering concerts.

Thanks

Bars with live music are a bit few and far between to be honest. For geetar stuff i'd recommend El Lokal or Hafenkneipe.
I'd be very intersted to hear of more places of their ilk.

Otherwise there are a few smaller concert venues which are pretty good for seeing live acts:

Abart
Kaufleuten (there's 2 smaller rooms which are good).
Volkshaus
Dynamo
Rote Fabrik

I'm going to see The Do at Mascotte on Sunday. It's more of a club so I don't know what it'll be like for live stuff.

p.s Avoid the ubiquitous Sasunnach Rat Club. The bouncers are a bunch of officious morons.

Sorry, but I only know of concerts.
You can find venues on zuertipp.ch or ronorp.net

Tested and recommended:
Abart (Which will close down soon)

Heard of:
Maaghalle, Helsinki

Zurich West:
Chollerhalle (If you consider going to Zug)
Bierhuebeli (If you consider going to Bern)
Fête de la Musique (If you consider going to Geneva)
Winterthurer Musikfestwochen (If you consider going to Winterthur)
