David Guillas

David "Space Beaver" Guillas (born February 27, 1979) is a Canadian guitarist, formerly of Giant Sons Rough Music, and hardcore punk band Propagandhi. He left Propagandhi to pursue a career as a teacher.

In early April 2002, Guillas played guitar for Giant Sons, a roots rock turned instrumental band in Winnipeg, Manitoba. The band broke up in August 2003, and ex-members of Giant Sons and Standstill formed a new band called Rough Music in February or March 2004.

In August 2006 he became a member of Winnipeg hardcore punk outfit Propagandhi, who are still active on the Winnipeg music scene.

A 15-track Giant Sons album titled Anthology was released on G7 Welcoming Committee Records in 2006, compiling their two earlier releases.

Guillas now teaches public school in Winnipeg's inner city.
