Kenny Rasmussen started hosting free, all-ages, daytime punk shows at the Bridgeport Library back in January for people who typically can’t make it out to bars and clubs to see great, local live music. Since then, his library gigs have picked up steam and have started popping up at other branches around town. This weekend his series will make its first appearance at the West Town Branch Library, and will feature the harshest lineup yet: noise-rockers Den headline, with support from hardcore band Rumores and crusty screamo trio Cracked Vessel, whose “Effigy Vessel,” off of last year’s Path IV cassette, is today’s 12 O’Clock Track. The band throws together a dizzying, black-metal-flavored blast-beat fury on their tapes, and this ripper is a prime example of the darkness they bring. These bands should be a riot to catch in a low-key library setting. As always with these shows, things kicks off at 2 PM, are free, and all ages are welcome. Check out “Effigy Vessel” below.
