U2 will continue its 360 tour in Germany tomorrow (Aug. 10) at Frankfurt Commerzbank Arena and fans can expect to hear new material.

The Irish band has returned from a two-month absence, which was caused by Bono's back injury. The U2 frontman required spinal surgery and the band was forced to withdraw from the U.K.'s Glastonbury festival.

At their Aug. 6 show at Turin's Olympic Stadium, Bono appeared to be fully recovered and put in an energetic performance, according to reports.

As reported on Friday (Aug. 6), the band relaunched their tour with new material in the set. U2 debuted the song "Glastonbury," which has since appeared on YouTube, and the acoustic ballad "North Star."

There was also a new piece of music for the set intro titled "Return of the Stingray Guitar," as well as a rare performance of "Hold Me, Thrill Me, Kiss Me, Kill Me" and "Miss Sarajevo" by U2 spin-off group Passengers.

The band also got the crowd to sing "Happy Birthday" to the Edge, who turned 49 on Sunday (Aug. 8).
