Brobdingnagian Bards
I am not usually the type of person to shamelessly advertise anything, but: Listen to the Brobdingnagian Bards. They are so great. There are two of them (according to their website, they are best friends), their instruments are a mandolin, an autoharp, and a recorder, which sound beautiful and unique together. And they have hilariously funny lyrics about things like Lord of the Rings and Star Wars and frog kissing. The geek in me is thriving and I love it! Here's their website: http://www.thebards.net.
