The Rainbow hosts these parties twice a year, events that we’ve cheekily rechristened Hairchella in the past. They make for great people-watching, usually while the sun beats down on the festivities. That said, this year’s lineup is particularly fun. There’s Sunset Strip hellraisers Warrant (albeit with their second singer since Jani Lane died), British glitter-stompers Sweet (albeit with like one original member), Van Halen tribute The Atomic Punks, theatrical heavy-metal puppet show Green Jelly, and punchy hard rockers Little Caesar. That’s a lot of party music, especially when considering the fact that entry is free (with a two-drink minimum). These Rainbow shows do a good job of resurrecting the decadent spirit of Sunset past, and Lemmy will surely approve as revelers take photos with his statue.
