Sunny days. Ocean breezes. Sandy shores. Leafy palm trees. Cool jazzy sounds spiked with pop, hip-hop, reggae, soul, calypso, even some street-corner swing, all in the service of positive vibes, spiritual uplift and “don’t worry, be happy” fun. Look beyond those alluring, seductive Surfaces, though, and that’s where the three-dimensional musical depth of the band’s principals, Colin Padalecki and Forrest Frank, truly shines through. With Frank on vocals and production, and Padalecki working on writing and arrangements, the pair have increasingly meshed their individual talents into one impressive whole. They’ve just released their second album.
