Hysteria! is a studio project founded in 2008 by vocalist Debbie Plein (aka Debbie Digital) and producer Marat Schacht. Initially the project developed around the live performance highlighting Debbie's voice and epic live guitar solos. However, in the course of time Debbie's voice gained popularity amongst trance enthusiasts which resulted in numerous collaborations with artists such as Andy Moor, Lange, Alan Morris, Jan Martin and many more. Today Hysteria! is mostly associated with Debbie's vocal collaborations within the trance music scene. Her voice can be heard on countless releases on virtually all big labels such as Black Hole, Armada or Enhanced.
