Max Havoc - May 26, 1985

The world famous Roxy. Weird to think how influential Van Halen was on the rock scene in L.A. One often thinks of their particular style of rock as an 80's thing, but the members of all those 80s acts (Motley Crue, Ratt, etc) as kids watched Van Halen at the Roxy in the late 70s. By the summer of 1980, Van Halen had three monster hit albums already.  By the time of this show, Van Halen released three more totaling six now. And since you were wondering who the hell Max Havoc were here's a short little bio: https://www.allmusic.com/artist/max-havoc-mn0001506034

The Cherry Bombz - April 17, 198?

A high profile band backed this female fronted hard rock group from the UK.  Watching a video of theirs reminds me what punk was created to oppose musically. Then there's Channel 3 who arguably bridged punk and glam. This was a hybrid that did not take off.

Megadeth - February 28, 1986

The Brigade aka Youth Brigade - February 21, 1987

Another great band at an out of town venue. I don't know about these odd names for these openers though - none come to mind.

SWA - January 24, 1987

Another from Los Angeles
