This music forum is a good place. I've bought a few dozen discs from recommendations here and have liked almost all of them. There are a lot of members with great taste in music.
On the commute to work in the morning, I like to turn on Morning Becomes Eclectic (
Morning Becomes Eclectic - KCRW) that airs on 89.9FM in Los Angeles. I like most of what they play and browse the playlist when something catches my ear.
Another local station I love is KJAZZ 88.1FM (
KJAZZ 88.1 FM | America's Jazz and Blues Station). Listening to KJAZZ got me into jazz; if I hear something I like, I'll pick it up.
vcoheda's suggestion of Amazon is a good one. If I love a record, I'll go to Amazon and see what other people liked. I've found lots of great music that way.
I've got a close friend out in Phoenix who plays in a band and has an encyclopedic knowledge of rock - I get a lot of recommendations from him. My cousin the vinyl hound (something like 6,000 LPs) is into trippy rock, jazz and roots - more recommendations there. And my friend and co-worker Cowboy Nick (
Twang with Cowboy Nick) keeps me up on country/roots.
I also dig around antique shops, junk stores, thrift shops, garage sales, and anywhere else I can find used vinyl. If it looks interesting, I buy it. I've found great music I never even knew existed. The turntable might have been the best investment I've made.
