Face it: Your life is a series of numbers, a cycle of digits — basically, one big pile of difficult math. And rarely is that fact explored with such exacting sincerity as it is on Thirty Days, Sixty Years, the second album from S.F. indie-pop outfit Blisses B. Over 11 glistening ditties — heavy with none-too-subtle Afropop influences, strong doses of Paul Simonism, and snippets of Cat Stevensy folk — these four lads do their numbers with a distinctively San Franciscan optimism, accounting for life's disappointments while leaving little doubt that the accompanying positives leave them pretty much in the black. The tight tendencies and song-centered arrangements on this self-recorded, self-produced, and self-released album make it a net gain, too, proving that this low-key, West Coast answer to Vampire Weekend has more than its share of valuable assets.
