Try Venice -- right on the beach -- just south of Santa Monica... This is where they film just about everything you see on TV these days -- every time you see something on TV at the beach in LA -- 99.99% of the time it's right on Venice beach -- that's where Baywatch was... As for music biz people -- probably the more down-to-earth people are near Silverlake, Echo Park area... but the real big money in the creative sector is happening around Venice...
...think about where you are going to commute though (if you are going to commute at all) -- because the traffic can be bad at certain hours... Venice is real close to the I10 and 90 freeways which is nice.
If you need a nice studio to stay in for a few months while you decide what you want to buy -- (cheaper than hotels) -- my girlfriend is moving out of her place in Pasadena this month. You could move in sometime in May -- and move out July or August w/ option to renew. Her place is pretty nice $750/month -- bay window in front, wood floors, very close to the 134, 110, and 210 freeways... and you can usually get downtown in 15-30 mins -- and to the beach in about 45mins. You are near a really beautiful park (Arroyo Park) -- they got horseback riding, archery, tennis club, golfing, jogging trail, baseball field... It's near all the fancy Colorado shopping, resturants, bars, and there is an excellent art museum 2 blocks away (Norton Simon Museum) -- this museum has way better contemporary art than the Getty if you are into art.... anyway her apartment is adjacent to a large business campus so there's some nice landscaping and parking... let me know if you are interestd ICQ#1622420
There are only 4 apartments in this building -- these are the only pics I have now...
