ok, im not linking to programmes or websites, too much work as i wrote sh!tloads of pages in here already about club scene in ZH.
when i say electro i mean that as a general term that includes techno, minimal, house, electro etc. check websites, check myspace of them artists n get an idea whats up.

indie means mostly indie-djays or_live that they have live gigs on.
also check programme on websites of particular club.

some of them might dont have a website...keep yo ear to the ground n watch for most modest flyers: black_n_white copies sticked with glue.
the glossier the poster is, the more stiff, commercial and unbearable the crowd, club, music will be there to be found. its a simple measure that will never change n indicates where to go (except mascotte, but karaoke from hell and some live-gigs are ok)

bar=bar with low-fi crowd in terms of less people in banking leisure wear, blackberry overkill, maserati car keys on tables, escorte service chicks at hand. etc. about 99,9% "you are not supposed to meet your boss"-certificate
