Lowercased and-ever-cool chickfactor magazine — manual for C86/Slumberland fangirls (and boys) and namesake of that one Belle and Sebastian song — is plotting a mini tour of shows in celebration of its 20th anniversary. The Bell House plays host to the pop caravan's requisite Brooklyn stop for a three-day spread boasting pretty much every band that has every influenced, say, the Dum Dum Girls. Tonight’s spectacle takes the cake, though, thanks to a reunited Black Tambourine helmed by chickfactor co-founder Pam Berry, an appearance by mighty NYC trio Versus, and your heart, melting.
