Brooklyn-based electro-socialite Maggie Horn has attitude for miles, best expressed through her singsong rapping and crooning on tracks by the likes of Curses!, Prince Paul, and Sharmaji. Her new Siren mixtape, compiled by Baltimore club legend Scottie B, showcases her mic finesse atop hip-hop, house, and B'more beats. To celebrate its release, the chanteuse performs tonight with friends and collaborators including Blaqstarr, Sammy Bananas from Fools Gold Records, DJ Teenwolf of the Ninjasonik crew, fellow girl-about-town Roxy Cottontail, and Scottie B himself.
