Heaven’s Jail (a band name I’m not too fond of) sounded pretty good as they opened for Sam Roberts Band but unfortunately the trio didn’t have much of an audience to witness them. As the fact the show was sold out might indicate, the crowd really was at the Mercury Lounge to see Canadian singer-songwriter Sam Roberts and his eponymous band perform. It was a special evening given the band’s latest album, the critically well-received Lo-Fantasy, was released that day. As Roberts announced, the band would celebrate by performing the entire 11-track album straight through, and return for an encore of a few earlier hits. Lo-Fantasy is a melodic, rock album that redefines Roberts sound with the addition of sinewy and gauzy club vibes that gives listeners more reasons to dance than to head-bang.
