Andi Deris is singer, songwriter, and multi-instrumentalist, best known through his work with German power metal band, Helloween.

Helloween is formed in 1984 in Hamburg by guitarist Michael Weikath, bassist Markus Grosskopf, drummer Ingo Schwichtenberg, and guitarist/vocalist Kai Hansen. The band’s early Keeper of the Seven Keys albums helped define the European power-metal sound with soaring melodies, dual guitar harmonies, and anthemic choruses. Over time, Helloween navigated personnel changes, stylistic shifts, internal tensions, and even tragedy with the loss of Schwichtenberg, yet they remained one of the most enduring and influential names in metal. In 2016, the group reunited its classic and modern lineups under the banner Pumpkins United, bringing together former vocalists Michael Kiske and Kai Hansen alongside the current members for a world tour and a self-titled album celebrating their decades-long legacy.

Andi Deris joined Helloween in 1994, following the departure of Michael Kiske. Before that, he co-founded the melodic metal band Pink Cream 69, earning recognition for his vocal power, range, and songwriting skill. Deris ushered Helloween into a new creative era with albums such as Master of the Rings, The Time of the Oath, Better Than Raw, The Dark Ride, and the modern Pumpkins United projects. His warm yet commanding vocal tone and dynamic stage presence helped stabilize the band through the shifting tides of the metal scene, and his compositional contributions have been central to Helloween’s continued evolution as one of the genre’s defining forces.
