This so-called electro-jazz duo out of Canada is not as inconsequential as your average smooth-jazz joe, but Four80East is no Dzihan & Kamien, Jazzanova or certianly not Flying Lotus. Rob DeBoer (keys, bass, guitar) and Tony Grace (percussion) bring a few new tricks to the game, but nothing you’ll remember after you leave the park. Still, for an aftrernoon of free music, you really can’t go wrong, especially if you happen to be hanging around Uptown anyway. Just don’t expect a wildly creative improvisational experience. Expect polite.
