College professor, visual artist, one-time City Paper panelist, and musician Terence Hannum is keeping plenty busy on the music front in 2015. Yesterday, the experimental drone-metal trio of which he is a part, Locrian, released 'An Index of Air,' the first single off the band's forthcoming album, "Infinite Dissolution," due out July 24 on Relapse Records. Clocking in at over seven minutes, the track slowly builds a repeated drum beat, droning synths, and buzzes and scratches before bursting open with guitar licks and Hannum's throat-straining screams. The shredding and rumbling percussion only intensifies before giving way to a noisy, grunge-y finish. Stream it below.
Back in April, Hannum and his wife, Erica Burgner-Hannum, released the debut 7-inch of their new project, The Holy Circle, on Accidental Guest Recordings. As you'll see when you stream 'Basel (About What Was Lost)' below, the song mixes layers of noise and throws in a beautifully looping pop-R&B vocal from Burgner-Hannum, a blend that is simultaneously avant-garde and immediately catchy. The Holy Circle opens for Azar Swan at Metro Gallery on June 16.
