Fans of Vampire Weekend and OK Go (and even Weezer) might take to solo artist Jared Mancuso, whose overall vitality, alt-rock rhythms and appropriately nerdy vocal tone add up to a consistent formula for each song. “Extraordinary,” with its big beat and heavy bassline, shows how well this Philadelphia-based artist’s voice fits snugly with his material. All instruments are recorded with skill, though we could have used a hotter mix on his lead vocals from time to time as, for example, on “So In Love” it seems like his voice is less in the forefront than it should be. “The Jungle” is perhaps our favorite song, a herky-jerky rhythm spearheaded by a shout-along chorus and witty lyrics. Fun stuff.
