Dengue Fever One of the great hidden histories of international pop music is Cambodia’s psychedelic rock scene of the late 1960s. A handful of scarcely annotated compilations have managed to document the past, but Los Angeles’ Dengue Fever aim to embody it in the present tense. This isn’t just a bunch of Western hipsters indulging in some obscure foreign fetish; organist Ethan Holtzman and his guitarist brother Zac loved the stuff they heard while visiting Cambodia so much they wanted to replicate it as authentically as possible — they even sought out a genuine Cambodian pop star to sing the tunes in her native Khmer. The elements that made their first albums two of L.A.’s local gems — swirling Farfisa organ, fuzz-covered guitars, squealing sax and singer Chhom Nimol’s haunting, high-pitched voice — are still present on Venus on Earth. only now played with heightened confidence, more muscle and slightly darker tones. Dengue Fever plays SOhO in Santa Barbara on April 17. SOhO, 1221 State St. #205, Santa Barbara, 962-7776

Ultimate Boarder Block Party That’s right, a block party. When was the last time Downtown Ventura saw one of those? Sure, there’s the Art Walks and stuff, but this celebration, coinciding with the big-time Ultimate Boarder event, is sure to be a party in the very literal sense of the word. On April 18, the 400 block of Main Street between California and Oak streets will shut down for performances by local bands such as My World, Tripdavon and Sublime tribute act Emilbus. There will be two skate ramps in use, surf art from 20 Ventura artists on sale, an autograph session from Ventura-born pro-surfer Mary Osborn and restored classic woodies on display.
