Spring Beaver was a concert put on by Youth Culture Promotions, an (the) Ottawa Underground group originally named "No Pigs".

Y.C.P. was formed in November 1981 to research the potential opening of a space for hardcore bands to play, record and socialize. A group was initially formed from two high schools but due to the posturing has pulled together small groups of kids over 20 miles. They (core=15) set up committees to handle sound, co-ordination and public relations (police, city, radio) and operated from January 2nd to March 20th, 1981.

The Spring Beaver concert was put on with the SUBVERTS from Chicago, the YOUNG LIONS (Toronto), and the RANDYPETERS, the ANGRY RAISINS, TARGET-21, and ATTENTION SPAN (all from Ottawa).
