Tom Petty has released "Somewhere Under Heaven," a once lost track he co-wrote with Mike Campbell for 1994's studio album Wildflowers.

"Somewhere Under Heaven" will be part of a new archival project titled Wildflowers: All the Rest.

"Somewhere Under Heaven" can also be heard during the closing credits for the new movie Entourage, which opens this week.

According to Petty, the release of Wildflowers: All the Rest features songs written between 1992-94 and was originally intended to be a double album. A release date for the new album has yet to be announced.

Petty will also be reuniting with his band Mudcrutch, whom he performed with pre-Heartbreakers.

The band will reportedly begin working on their first new album in seven years later this summer.
