Blood Sister are a band from San Francisco, made up of two other bands I’ve never heard of – Night Manager and Ganglions. They had two tracks available about 3 months ago ‘Why Would You’ and ‘BART SIMPSON’. Today you can get another 2, ‘Not a Resident’ and ‘Psychic Flashes’ from their Bandcamp page. They use pop culture imagery from the 80s and 90s but their music is mostly very harsh arpeggiated guitars and distorted vocals with lots and lots and lots of reverb and delay. They have a pretty unique vibe. Brilliant stuff.
Their tumblr is brilliant.
