The first minute of “Hey Mamma” pays major homage to the Beatles of a certain era you can probably guess by looking at the photo. After the first minute, as Hunter S. Thompson might say, it gets a little strange. But strange is good, and Kay Kay manages to toss around strings, percussion, and even what sounds like a player piano to spritely effect. The songs on the band’s MySpace page are equally confounding yet somehow appealing to the ears. Kay Kay will be coughing up a cassette-only EP soon, so pick it up and, hop in your 10-year-old Subaru and crank it until you can’t hear the engine noise.
