Formed in 2005 by Jeff Anderle and Jonathan Russell, Sqwonk has given numerous performances at a wide range of venues and events including San Francisco, New York and Washington DC. Sqwonk has received grants from the Northern California Composers Commissioning Program, Subito, the San Francisco Friends of Chamber Music, and the San Francisco Conservatory of Music. As a consequence of its mission to develop a new repertoire of bass clarinet duos, Sqwonk has commissioned and premiered works by some fifteen composers and still counting. In 2006, Sqwonk received a Faculty Development grant from the San Francisco Conservatory of Music to fund its first CD, which was released in the fall of 2007. Its second CD, Black, was released in March 2010, and was funded through a grant from the San Francisco Friends of Chamber Music.

In July 2008, Sqwonk appeared as a guest performer at the Bang on a Can Summer Institute in North Adams, MA. In December 2008 at Washington D.C.'s Great Noise Ensemble, and made its New York City debut at Gallerie Icosahedron. In 2009, Sqwonk made its debut appearance at The Stone, New York’s venerable experimental music venue, and led a master class at Princeton University.

Sqwonk is an affiliate of the San Francisco Friends of Chamber Music.

He also plays in, composes for, and is a founding member of the Sqwonk bass clarinet duo, and is a co-director of the annual Switchboard Music Festival.
