Scene reports. Regional styles. It all seems charmingly antiquated these days, given how social networking cross-pollination has transcended space and time. But with a hyper literate, tightly wound, and irreverent brand of post-collegiate rock, Bent Shapes may just be the most quintessentially Boston band in recent memory. Since forming the group under the name Girlfriends in 2009, principal songwriters Ben Potrykus and Andy Sadoway have largely ignored indie trends leaking from the ''industry cities'' in favor of churning out earnest, expertly-crafted pop and post-punk laced with ''some of the tightest punk poetry around'' (Liz Pelly).
