A cool, early-hour experimental music night is happening at the Miniplex at 6 p.m. Australian/Los Angeles duo Stevie Richards and Mike Meanstreetz bring the traveling sound to the stage, where they will be supported by two local acts, synth-popping maestros Elegant Humanoid and sound-blaster, tone bender IDYL. $5-$10 sliding scale, and if you stick around after, there will be karaoke. An hour later, the Arcata Playhouse is the place to be if you are in the mood for a different sort of sound from Australia. Bobby Alu is a multi-instrumentalist who has devised his own style of island soul music, drawing heavily from roots reggae and laid-back folk traditions. ($23, $21 Playhouse members).
