Our church has a monthly CD roundtable where we do potluck dinner and everybody brings a CD to play a couple songs. Half the CDs go home (temporarily) with a different person.

I also listen to the interviews of the (semi) popular musicians that I already listen to. I love when they say what influences them and what they are currently listening to. Jimmy Buffett turned me onto Zachary Richard, who turned me on to Beausoleil who turned me onto . . .

Guest performers on albums is another way. That's one way I learn about new Celtic performers.

The there's all the music programs on Public Radio.
