Since 2005, XPQ-21 have officially been a four-piece band live on stage, though the line-up is a fluid and rotating one for creative and logistical reasons. Jeyênne, Mask aka Martin Hillebrand on keyboards/sequencer/sampler, plus, occasionally Annelie Bertilsson, André Hartmann or Alex Gsell on guitar, and Claudia "Killer" Lippmann, Kebbasasch or Moritz Zielke on drums. Sometimes the line-up consists of just two people, Jeyênne and Mask. The only constant in the line-up is of course Jeyênne.
