U2 have released the second song in their digital series, U2 To Love and Only Love – Deep Dives and B-Sides.
This time it's a live acoustic version of "Staring at the Sun" from 2001 in front of 80,000 at Slane Castle in Dublin, Ireland during their Elevation tour.
The song originally appears on their ninth album, Pop, released in 1997.
There are 10 more tracks yet to come this year -- songs that until now were only available on vinyl, CD or cassette.
Saturday U2 released their most recent song, "Atomic City," as a limited-edition two-track exclusive 10-inch vinyl for Record Store Day.
