I’ve lived in Long Beach, California on a couple of occasions. Once in 2002, and again, from 2006 to 2007.
When you mention Long Beach, people always want to mention Snoop. But I think you have to look outside of hip-hop (and the Rivera family) to really find some of the best music that Long Beach produced; Sublime. A recent roadtrip and a random mixtape reminded me how great a band they were. Check out a discography, here.
