This Friday night, get ready to have your face melted. The Austin-based rock trio Megafauna has been just under the radar of indie rock fame for years, winning critical love with their 2014 album, Maximalist, and touring all over the country. They’ve proved their mettle in the brutally competitive Austin music scene, with frontwoman Dani Neff even earning the Austin Chronicle’s “Best Austin Musician: Electric Guitar” title in 2012. The Megafauna sound, which flirts between math rock and sludgy stoner metal, is defined mostly by Neff’s multi-genre guitar prowess and her trippy, poetic lyrics. Think The Breeders with a little more Kurt Cobain and a lot more psychedelic drugs. Megafauna is currently on tour for their fourth album, Welcome Home, which comes out May 27. The two singles released earlier this year, “Desire” and “Panpsychist,” feature plenty of Neff’s pedalboard wizardry and blistering guitar solos, promising good things. They’ll be playing tunes from the new album and selling advanced vinyl and CDs on this tour, so make sure to stop by the merch table. Megafauna headlines at Sister (407 Central NW) on Friday, May 20. Also playing are Red Light Cameras and Leeches of Lore. This 21+ show starts at 9pm.
