There’s nothing I love more than All Hallows’ Eve, rad music and even radder art (also on that list: instituting a false lexis). And the Big Art Show Halloween Spooktacular exhibit at Pterodactyl tonight is like an idiosyncratic flare-up of all three. Well, OK, it’s not on Halloween, but the minds behind the Kensington space did so cleverly allude to the sacred day in the show’s title, and that’s good enough for me. Still, designations are trivial when compared to the local rhythms that’ll vibrate threw your body while trolling the loft gallery – the blithesome folk of The Great Unknown’s alt-Americana missives, the incisive disquiet of Lion Versus’ alt-folk allegories, and the spectral jowls of A Stick and A Stone’s esoteric chronicles, plus the bemoaned strings and pining plucks of Baltimore’s indie-folk squad, A Cat Called Cricket.
