Joanna Newsom and the Ys Street Band

Joanna Newsom & the Ys Street Band is an EP by Joanna Newsom, first released on April 9, 2007, via Drag City.

The EP was recorded and mixed over three days at The Plant Studios after Joanna had cancelled three consecutive shows due to a lost voice at the end of her seven-week-long U.S. tour. It contains one previously unreleased song, "Colleen", and new arrangements of two previously released songs; "Clam, Crab, Cockle, Cowrie" from Milk-Eyed Mender and Walnut Whales and "Cosmia" from Ys.

The album title is a pun on the E Street Band, a musical group famous for backing up Bruce Springsteen.
