Blink-182’s Tom DeLonge has regrets about how their album, Neighborhoods, turned out. He said he was too “heavy-handed” in trying to change the band’s sound for what became his final album with Blink.
After making music with Angels & Airwaves, he felt that was his outlet for the heavier music. And no longer feels the need to push Blink in that direction.
Travis Barker has stated that Delonge was so “careless” while working on the album, that he didn't even listen to the mixes or masterings.
