'they blew'em off the stage'

Ten Years After opening for Peter Frampton.
My memory is a little less clear on this, you know the times were different then, but I seem to recall King Crimson opening for Golden Earing.
I wasn't there, but, it's been reported that Jimmy Hendrix opened for the Monkeys.

Jay Ferguson, ex of Spirit, blew the Doobies off the stage on a nightly basis in support of his Thunder Island album. I used to work for Jay as his lighting designer. He had a remarkably tight band and he was a one man wrecking crew on stage. The press coverage started to become embarassing for the Doobie Brothers so we came off their tour and started headlining our own in smaller venues.

In 1987 I was in the front row when The Cult opened for Billy Idol.

Idol was pretty good, but The Cult just brought the house down.

Wow, I have to go way back for this: Muddy Waters, Willie Dixon at al. as warm-up to the Rolling Stones.

Pacific Gas and Electric opened for John Mayall at the Kinetic Playground (Aaron Russo's Electric Theater) in Chicago around 1969 and came out smokin'. I don't remember Mayall's lineup of band members at the time but do remember him being upset with the bass player's volume. PG & E went on to return many times, gathered a loyal following and never had a bad night any of the many times I heard them.
