David Guillas

David "Space Beaver" Guillas (born February, 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. He currently plays guitar in Agassiz, an instrumental rock band.

Career
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. Guillas left Propagandhi in 2015 in favor of his teaching career, however it was originally intended that he would still perform on studio recordings. However, his successor – Sulynn Hago – was credited as a full band member on the band's next release Victory_Lap_(Propagandhi_album) and Guillas only provided additional guitar parts credited as a "Propagandhi alumnus".

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

Shortly after leaving Propagandhi, Guillas started playing and writing new music with Derek Hogue (formerly of G7 Welcoming Committee) on drums. They were joined in 2017 by Ryan Nash on bass and keys, settling as an instrumental rock trio called Agassiz. They have released four EPs.

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