Ezana Edwards used to rock in the Brooklyn lo-fi garage band Night Manager, but since that group’s dispersal he’s moved to San Francisco, started a solo project called Blood Sister, and recruited a live band featuring members of Ganglians, The Mallard, and Warm Soda. Blood Sister’s self-titled debut, recorded entirely by Edwards, arrives about a month from now. Lead single “Paralysis” lives up to the project’s stated goal of being as loud as possible at all times. It’s an intense yet sugary guitar rager with a crystalline gleam that clatters with an industrial edge. Gnarly guitar solos and crunchy power chords intermingle with eerie keyboard lines and a violent drum part to blistering effect. Hear it below.
