From the Motown stomp of “Dirty Dream Number Two” to the Paul Simon shuffle of the title track, there is more musical texture on Boy than Sinister, but much of this was already explored on the EPs, which means Arab Strap essentially consolidates the group’s talents. Murdoch recedes from the spotlight on occasion, letting Steve Jackson deliver two music-biz spiels and giving Isobel Campbell space to shine with the lilting “Is It Wicked Not to Care?” All three songs are highlights, but Murdoch’s songs still attract the most attention. His vicious wit, often overlooked in favor of his poetic narratives, surfaces on the title track, while “It Could Have Been a Brilliant Career” summarizes his effortless gift for elegant melancholia. Such small, precious gems are what Belle & Sebastian are all about, and The Boy With the Arab Strap offers another round of timeless, endlessly fascinating folk-pop treasures.
