There are scores of shows at POP Montreal, more rare are the MOMENTS, when everything is beautiful, everyone is engaged, your throat tightens and you smile to yourself because you know that this is truly special. Leif Vollebekk's Friday night rooftop set was such a moment. Panoramic views over Montreal, gothic rooftops and the Mt Royal cross pushing up into the cloud line, the sun setting golden orange in the Montreal north. On a Persian rug island ringed with electric candelabra, Vollebekk sets up, invites the tiny crowd to pull near. What follows is a deeply intimate hour of music, Vollebekk alternately behind the keyboard and guitar, traffic from Parc Avenue offering the occasional punctuation.
