Charlotte, NC, math rock band Cuzco will be releasing their debut LP, Sketchbook, on April 19th through Refresh Records. Today we’re excited to bring you the album’s first single, the six-and-a-half minute “Old Dog.” It twists and segues through bursts of horns and twinkling riffs that would make Toe. or TTNG proud with a bit of Clever Girl inspired jazz flavor. Check out “Old Dog” below, and if you like the song, be sure to preorder Sketchbook.
