Now that we’re 40 years past LaMonte Young, 30 past Brian Eno, and more than 10 past Christian Fennesz, it’s hard to imagine what’s left to do in the world of ambient. And yet Christopher Bissonnette’s second CD touches the soul and tugs at the heartstrings in ways that are both familiar and different than his first records. Tracks like “Provenance” and “The Colonnade” sound wrapped in gauze while the muffled bells on “Tempest” border on sinister and somehow manage to be sublime. The whole thing cries out for your attention in a way that ambient isn’t supposed to–making this a more challenging and wonderful album because of it.
