We previewed the first track  “Angel With No Halo” from the new  Nostalgia 77 album back in November, now we have another tune to get excited about.“What Do You Know” features vocalist Josa Piet, who appears on nine of the eleven cuts on the album? The track is a light, breezy jazzy number with lovely horns and subtle guitar picks.While the track is jazz, in essence, Piet’s rich vocals also give off a slight feel of bluesy folk.You can stream and download below and when you’re done Preorder the album over at iTunes
