I sing bass with the Illini Statesmen Barbershop Chorus. I've been a member of their parent organization, SPEBSQSA (now, sadly, simply the Barbershop Harmony Society), for about six years. I'm currently serving as the webmaster for the chorus.
I have also sung bass with Tesseract, the 2005 Illinois District Collegiate Quartet Champions. We competed at the international level at the Salt Lake City convention in July of 2005. By the time internationals came around the next year, I was too old to compete at the collegiate level, so they found themselves a new bass.
