Los Angeles: American rock band Green Day has revealed their plans to release a brand new single titled "Bang bang", next week. It will be the first new song from the the band -- which is popular for songs like "Boulevard of broken dreams" and "Wake me up when September ends" -- since their surprise Christmas single "Xmas time of the year" in late 2015. The band's frontman Billie Joe Armstrong took to his Twitter and Instagram accounts to announce the news on Monday. "Dear friends! Green Day is putting out a new single called 'Bang bang' on August 11. Stay tuned for more details," Armstrong wrote. The announcement comes after months of subtle hinting by Armstrong, who released both a photograph in the music studio in January along with a video clip exploring the studio, taking a look at all of the instruments that may be being used in the creation of the group's new material.
