When I was about to have my first kid, back in 1997, a fellow editor at Wired told me that there were really only two downsides to having kids: 1) The lack of sleep, and 2) kid music. He was right.
Fortunately, a few kid bands are excellent. My favorite is Gwendolyn and the Good Time gang. Their lyrics are funny, and the music is clever and engaging. We saw them perform live in the woods of Topanga Canyon on Sunday, and it was the best live music performance I've seen since Joe Strummer played at the Troubador shortly before his untimely death. They put on a lively show.
If you have young kids, you owe it to your sanity to microwave the Barney and Gymboree CDs in your possession and seek out Gwendolyn and the Good Time Gang. Link
