German progressive thrash band End Amen resulted from an unexpected allegiance forged between d**hrow guitarist Uwe Osterlehner and Psychotic Waltz members Dan Rock (guitar) and Norm Leggio (drums), while touring together with their full-time band concerns. With Osterlehner also handling vocals and ba**ist Siggi Blasey (of Crash Museum) brought along for the ride, the members of the newly baptized End Amen collaborated on a one-off 1992 LP entitled Your Last Orison, then went their separate ways. ~ Eduardo Rivadavia, All Music Guide
