Don't let the dumb name fool you. The guys in Slightly Stoopid, a veteran SoCal outfit, are serious musicians. For more than 20 years now, they've worked in the shadow of similarly eclectic-minded musicians such as 311 and Sublime. They even initially signed to the band's Skunk Records. The band plays an incredibly dance-able fusion of reggae, punk, hip-hop and funk. On a track like "Top of the World," they perfectly balance jazzy grooves and lazy vocals. While there's a bit of a Jack Johnson vibe to the track, the bluesy guitar riffs keep things lively. These guys are consummate players — expect to hear them stretch out and jam a bit during the show. The band headlines this weekend's music festival at Nelson Ledges. Special guests Stick Figure and Pepper share the bill. Weekend passes are $120 in advance, $140 at the door. That includes camping.
