Aptly named mariachi-metal quintet Metalachi calls Hollywood home, but their schtick is more Ciudad Juárez than Rodeo Drive. High camp and stories of horse tranquilizers and hotel rooms dominate the biographical info hyped by the act. If you ever wanted to hear mariachi renditions of Dio’s “Rainbow in the Dark,” Motörhead’s “Ace of Spades,” Iron Maiden’s “Run to the Hills” or Led Zeppelin’s “Immigrant Song,” this concert is for you. Fashion, showmanship, chops—Metalachi has their niche carved out. Don a sombrero, zebra-print spandex and leather when Metalachi rocks Low Spirits (2823 Second Street NW) on Wednesday, Sept. 18. The 21-and-over show revs up at 9pm and runs you about eight bones.
