Fire music of the highest order. Heart of the Ghost’s Summons kicks off with a cry of wild abandon: “Wooooo!” And then we’re off, with Jarrett Gilgore (alto and soprano sax), Luke Stewart (upright bass) and Ian McColm (drums and percussion) converging in a flurry of densely packed sound, each player racing to the finish line. Or maybe “racing” isn’t quite the right term. There’s no sense of competition here. This trio — even in their stormiest moments — is moving as one, displaying extraordinary interconnectedness throughout the album’s four tracks.
