U2 released a previously unheard song off their upcoming How to Dismantle an Atomic Bomb (20th Anniversary) box set today (Thursday).
The song, "Happiness," was recorded during the sessions for How to Dismantle an Atomic Bomb. In an excerpt from an interview with Zane Lowe, The Edge and Adam Clayton told how The Edge has carried around a rough mix of it that he liked in a large leather shoulder bag until he was finally able to convince Bono that the song was worthy of release.
You can find the new song on YouTube and the interview excerpt on U2's Instagram feed. How to Dismantle an Atomic Bomb (20th Anniversary) will be released on November 22nd as a 5-CD box set or in an 8-LP Super Deluxe Collectors Box Set.
