Tom Petty's estate is working an archival release related to his 1994 Rick Rubin-produced album Wildflowers. Petty, who died in 2017, submitted a double-CD's worth of material, but the record got trimmed back to one disc. Now it looks like we're finally going to hear the rest of it. “The family and all our engineers and the Heartbreakers have been circling around this project and making it as delightful and completist as possible,” Petty's daughter Adria tells Rolling Stone. “We’re really pleased to be able to share the second half of the Wildflowers double album. But there are also completist versions of how the sessions evolved. My dad was prolific at that time and there was so much recording done. Coming off the ‘Last Dance with Mary Jane’ session, it was a complete evolution of how dad recorded and how he made space for his own feelings. Wildflowers was very personal for him. He wasn’t hiding behind anything.”

While we wait on details, they've shared the 8-track demo of hit "You Don't Know How it Feels." While stripped down just a bit -- no percussion -- the bones of the track are all there, including the harmonica hook, plus you might also note some different lyrics. They've made an animated video for the demo, directed by Blaze Ben Brooks and Aaron Hymes, and you can watch that below.

Meanwhile, the Petty family issued a cease-and-desist order on the Donald Trump campaign after Tom Petty & The Heartbreaker's song "Won't Back Down" was used at the Trump Tulsa rally last weekend. "Trump was in no way authorized to use this song to further a campaign that leaves too many Americans and common sense behind," the family said in a tweet Saturday. "Both the late Tom Petty and his family firmly stand against racism and discrimination of any kind. Tom Petty would never want a song of his used for a campaign of hate. He liked to bring people together." Read the whole tweet below.
