BedtimeMagic: fast and murky hardcore with organ instead of guitar. They hit the occasional crisp, almost funky groove and remind me of ’80s industrial mixed with, like, Man Is The Bastard. I’m intrigued. Greylock: dramatic, creepy-crawly sludge dirges, howling up from the fuzzy abyss. Both bands are from the Boston area, and they each cover one of the other band’s songs. –Chris Terry (torjohnsonrecords.bandcamp.com)
