On May 7, 1967, the “Psychedelic Soundburst” (or Sound-Burst) took place at Aldrich Arena. The show, emcee’ed by KDWB’s Charlee Brown and Earl L. Trout III, was billed as the “Biggest Dance in the History of Aldrich Arena” and promised the world’s best light show – the Fillmore Light Show.  The Music Scene reported that the show was presented by Rich Hanson, who planned another for June called “School’s Out – Book Burning Blast.”  (did this happen?)

Featured performers were:

• The Del Counts
• The Hot Half Dozen
• Danny’s Reasons
• The Litter – “a group that equals The Electric Prunes in sight and sound”
• Grasshoppers – Headliners
• Happy Dayz(e?)
• Youngsters
• Sir Raleighs
• The Chancellors, just home from triumphant tour of Kansas
•  Dozen
• The High Spirits
