Hansen & Friends: Thank You Wacken Live

The shows celebrated the greatest hits from three decades and offered a breakneck trip through time and the entire HELLOWEEN repertoire – including songs, the band hadn’t played live for a very long time, or even never before. The recordings took place during the band's Pumpkins United World Tour (2017–2018), with former members Michael Kiske and Kai Hansen joining Helloween's line-up. The main concert was recorded on 9 December 2017 in Madrid, Spain and the bonus tracks in Chile, Brazil, Czech Republic and Germany. Extra material includes a band interview, as well as LED content and animations shown during the shows.
