Permanent Wave Philly joins forces with Sara Sherr of Sugar Town to put on their 2nd ever Sound Wave showcase at Cha-cha’razzi tonight. The performance series benefits Hollaback! which is a movement dedicated to ending street harassment through mobile technology, and Sherr lined up a solid crew of female artists to perform. At just 21 years old, Attia Taylor has already released 3 well-received EPs filled with dream-pop, soulful chants, and wistful trance. And after trekking down to SXSW, she is back and in the process of finishing up her first full-length album. Catnaps took a break from SXSW this year, but the local indie twee outfit will be making up for it when they play the Human BBQ at PiLam, throwdown at NYC Pop Fest, and delight you with their catchy melodies tonight. The evening will also feature the enchanting harp and multi-instrumentals of Liz & The Lost Boys as well as Bike Crash which features former Attia Taylor collaborator Meghan Filoromo.
