Four Shadow comes from the same gene pool that produced contemporary a cappella heroes Rockapella, the House Jacks and Five O' Clock Shadow. The ear-friendly pop rock of original tunes such as 'Little Mouse, ' 'Wendy' and 'World To Me' are kicked off by the crisp snap and articulation of the vocal bass and drums, who work it with tight precision. Savvy production and arranging delivers points, creating a full and dynamic sound. The group spins rap with 'George' and then careens into the off-kilter country polka feel and impolite lyric of 'If' ('if you were a song I would not sing you' is the most civilized, and that's putting it kindly). A few covers Ð Paul Simon, Dave Matthews Ð round out the set. We like it.
