A night with Sleigh Bells and Brazil’s CSS doesn’t need anybody’s help, but add Bosco Delrey and things get even better. “20 Flight Dub,” included in his full-length debut Everybody Wah (out on April 26 on Mad Decent and mixed by Doug Easley of White Stripes, Sonic Youth, Pavement, Wilco, and Cat Power fame) has been described as Bill Haley doing dub. More broadly, Delrey, who’s been remixed by the Beastie Boys, is Elvis doing technobilly. If you can’t wait until the 26th to get the album, get the digital versions of his two 2010 seven-inch releases (“Wild One/Evil Lives” and “Space Junky/My My Racecar”). “`Bosco is` a sort of garbage-can Elvis from New Jersey,” said label boss Diplo. “ ... teaspoon craziness, a pinch of rockabilly, and full cup of soul dressed in a leather jacket.” You see? The “everything in music has been invented” mantra is only a myth. $17.50 in advance, $20 at the door, doors at 8pm, White Rabbit, 2410 N St. Mary’s, (210) 737-2221, sawhiterabbit.com, detourtickets.com.
