Hans Ziller (born 18 May 1959) is the master mind, founder, lead guitarist, backing vocalist and primary composer of the German 1980s melodic hard rock band Bonfire.[1] He founded the band called Cacumen (a predecessor of Bonfire) as a teenager in 1972. In 1989 in the middle of working on Bonfire's third album Point Blank – which, like the earlier albums, was produced by Michael Wagener – Hans Ziller left the band because of insurmountable differences with the management and the rest of the band and began a project of his own called EZ Livin’. 1993 he continued with Bonfire.[citation needed]

Wikipedia: Hans Ziller in 2014 resurrected EZ Livin’ for a solo venture that was originally planned to be temporary. On 11 January 2015 Ziller reformed Bonfire. The initial album of the new line-up, Glörious, made the German top 50 GFK album charts, and at the end of 2015, Ziller signed a new contract with the UDR/Warner label. In 2016, Bonfire released the album Pearls on UDR to commemorate the 30th anniversary of the band and embarked on an extended tour to promote the album.
