Ex Input:
Verify if the sentiment of the following document towards the entity Tom Petty is Neutral . That was some of Petty’s magic  hiding something exotic and distinctive in plain sight  as personal as he was populist. He gathered a lot from his Traveling Wilburys contemporaries  like the mystical George Harrison and the cheeky Bob Dylan. But with the eclectic Wildflowers  one of the best albums of his career  he managed to carve out his own cool little lane for his next 23 years. That same year  in 1994  Johnny Cash also entered into Rick Rubin’s atmosphere with American Recordings; two years later Tom Petty and the Heartbreakers were the backing band on Cash's follow-up American II: Unchained  and the group sounded fucking awesome. As the Man in Black was initializing his descent into his final decade — the wits and hurt of age setting into his vocals — the Heartbreakers were arguably peak Heartbreakers. I like to think each artist paid witness to the other’s evolution  passing through and yet part of the other’s tradition for always.

Ex Output:

yes
