Just to give you more a feel of the Glockenbach:
It's an old working class area of Munich so it meant (until recently) that the rents were low-ish. This attracted in a lot of creative people doing stuff with music and theatre, spaces for art venisages etc too. This is in contrast to the jointly administered Gärtnerplatzviertel which from it conception had a very bourgeois feel.
Locally there a VERY large lesbian and gay community and that certainly is a big influence.
Just of the top of my head:
Kitchen and Registratur. Kind of alternaveish clubs in old council buildings no longer used. Some good acts and a different feel to more regular clubs If you keep your ear to the fround there are other one off unofficial parties happening locally.
2nd hand and new record specialist stores on Auen, Fraunhofer, Jahn and Colluseum Strasse
Altenative cinema / theatre on Fraunhoferstrasse. Arena cinema on Hans Sachs Strasse plays a slightly less commerical programme.
Bars like Die Bank and Excess on Jahn Strasse I forget the name of

have changing DJs in playing their music and at Die Bank there are also arty things going on.
That's just the things that come immediately to mind within a 5 minute walk of my house.
The PROBLEM however is that here there is a vibrant commuity created and suddenly that gets attractive to those with money. There has been a massive influx of those with money into the area over the last few years, properties have become more expensive. The old Munich working class seems to be dying out or moving away meaning sadly an end to many of those tiny little boozy pubs where I leart my German.

In their place and replacing old fashioned "mom and pop" stores are exclusive restaurants and bistros and shops selling expensive faashions and "lifestyle" accesoires.
I mentioned the Domackstrasse above, a DJ friend of mine has a studio out there.
But that might well be closed down as the drains are busted and the city is fighting with the federal government about who is responsible. Together with the 2 clubs I mentioned about and the the club complex at
Ostbahnhof it is an example of how spaces are being used in Munich right now. As buildings are no longer needed for their primary purpose they are given a few years of life as "entertainment" venues.
But this is a short term thing. There is no investment made and sooner or later they close for major re-development as prime real estate.
The city IS planning a new cultural facility with bars and clubs etc in the far north of Munich but it will be artificcially created and not so accesable (even from the northern side of the city) without a MASSIVE improvement in public transport at night.
Oh and worth a mention is the Feierwork complex near Heimerannplatz.
