CAKE

(This is John McCrea, the lead singer of Cake. After one concert, I managed to catch him out back and somhow spluttered, of all questions, "do you like Kurt Vonnegut?" Why I asked that, I don't know. For the record, he said yes).

Cake has been my favorite band for a hugely long time. Once, in high school, I drove three hours and went through the giant pain that was booking a hotel room as a minor (it involved some calls from my mom) because I wanted to see them so badly. My favorite game is "guess the Cake song" (mostly because I get it right pretty much every time). Needless to say, I'm obsessed.
Part of the reason I keep coming back to Cake is that not only is their music amazing, but they are a band that actively cares about things. A glance at their news page quickly reveals that issues like big oil, global warming, and Washington politics are important to them. They definitely have strong opinions and aren't bashful about being upfront about them, but they're not just talk...they actually do things, like encourage concert-goers to carpool, give away trees at concerts, and install solar panels on their studio. Here's a video about their solar panel installation:

Pretty cool, yeah? I'll leave you with one of my favorite songs (predictably, it's impossible for me to choose just one). Enjoy!
