Since being turned on to them by my college roommate, I've been a big fan of They Might be Giants, whom if you aren't aware of them (for some strange reason) are essentially the godfathers of geek rock - starting out way back in 1982.  Modern geek musician superstars such as Jonathan Coulton and MC Frontalot frequently list them as a huge influence.  Even if you don't think you know them, you've probably heard their music.  "Istanbul (Not Constantinople)" and "Particle Man" were featured on an episode of Tiny Toon Adventures back in the 90's, and more recently, they've written and performed the theme music to shows like Malcom in the Middle and The Daily Show.  But really, if you want to read up, I can just direct you to Dr. Wikipedia for more.

I'd like to share my favorite rendition of what many of their fans consider their best song: "Birdhouse in Your Soul".  This comes from a 1990 appearance on The Tonight Show (Jay Leno guest hosting).  The quality is VHS-tacular, but the brassy sound of Doc Severinsen's NBC Orchestra is just spectacular, and even includes a great solo by Doc himself (such a pure sound).  Sure, John F. gets a little too excited when he joins the singing near the end, but he recovers quickly, and I can't help myself from tapping my foot to this uptempo version - more than even the original one.  So please enjoy my favorite version of my favorite song from TMBG... and look into more of their stuff if they're new to you.  You won't regret it.
