Bloodlined Calligraphy is that comparative rarity, a thrashy metalcore band with a female lead singer doing the usual Cookie Monster vocals instead of a burly, deep-voiced dude. Bloodlined Calligraphy is fundamentally an extension of an earlier metalcore act, Friction. Formed in Ypsilanti, MI, in 1998, Friction had been developing a following, but regular lineup changes disrupted their momentum.
