Edge shared his thoughts on Songs Of Experience during a radio interview today on TodayFM's The Mix Up show (starts around 29:00).
"The question of when the album gets finished is very open," he said, adding that the band is busy with tour prep right now. "We are pushing hard to try to get the album done and out within, we hope, 18 months or so, but it's so hard to predict. ... (W)e don't want to release anything that we haven't had a chance to really finish to our satisfaction. ... It's not a case of putting six weeks aside to make an album. It's that we want it to be everything we want it to be."
