Some bands have to make daring, even drastic changes from album to album to find a sound they can call their own. Not the Black Heart Procession--on their 1998 debut, 1, they seemed to arrive fully formed, and if there were any progressions to be found on their next two full-lengths, they were about as noticeable as continental drift. Then came 2002's excursion into lounge-Latin eroticism, Amore Del Tropico, followed two years later by a jury-rigged collaboration with Dutch prog rockers Solbakken for Konkurrent's "In the Fishtank" series, both of which sounded like major seismic events. But Black Heart's newest, The Spell (Touch & Go), is a return to basics: a patina of weathered romance, grandly melancholic arrangements, Pall Jenkins's plaintive howl. Not that everything about the new disc is a downer: the video for the first single, "Not Just Words," actually hits joydirt. If there's anything better than watching Shannyn Sossamon spin around on a mountain, it's watching four of her spin around on a mountain. The Castanets and the Devics open.
