Tom Petty has released a previously unheard track entitled Somewhere Under Heaven, which he recorded in 1994. It's available through digital retailers, and a teaser can be viewed below.

The song was co-written with Mike Campbell for 1994 album Wildflowers when Petty and producer Rick Rubin envisioned it as a double-length release, but remained unheard until now.

It will feature on Wildflowers: All The Rest, which includes more unheard material written between 1992 and 1994. No release date has been confirmed.
