When I was in Hawaii, our friend Tim introduced me to http://www.pandora.com/. It's a wonderful website where you can put in a favorite group and it pulls up artists that are similar musically. Tim had put in Van Morrison so we had a great time listening to not only Van Morrison but Allman Brothers, Grateful Dead and others on the back verandah while we were relaxing and looking across the bay trying to see whales or spinner dolphins.
When I came home this weekend, I logged on to Pandora and put in the California Guitar Trio as a place to start. The comparables that Pandora came up with were wonderful--musicians I had no clue about. So far my favorite is a guitarist named Preston Reed. He has a very distinctive style. I hope you enjoy it as much as I have.
