Galleries: Two outstanding pairings, at Pentimenti and at Locks

It's not often that a two-person show catches both of its artists on a perfect wave - or, rarer still, unites two who make each other shine - but Pentimenti Gallery's pairing of Jackie Tileston and Jedediah Morfit does both. While Tileston envisions the landscape as a place of ever-expanding possibility, Morfit uses it to evoke the inevitable passage of human life on Earth as it was viewed a couple of centuries ago, with some odd goings-on along the way.
