A decade of scathing rock at breakneck speed can really take it out of you. So three former members of local spazz-core demons the Blood Brothers—vocalist Jordan Blilie, bassist/keyboardist Morgan Henderson, and drummer Mark Gajadhar—needed to decompress. After a short respite, they took on ex-Shoplifting guitarist Devin Welch and formed Past Lives, their new weapon against apathy and boredom. Clangorous and angsty, Past Lives create a more subtle, angular brand of rock. They're mellower than Blood Bros ever were, but their artful thrusts cut just as deeply.
