Gregg Xenakes has 2 Geoff Tate concerts.

Originally from Stuttgart, West Germany Geoff Tate (born Jeffrey Wayne Tate, January 14, 1959) was a founding member of Queensrÿche in the mid-1980s. He was fired from the band in 2012 and went on to form "Geoff Tate's Queensrÿche." in 2014, however, the band was forced to change its name when Tate lost the branding rights for "Queensrÿche" to his former bandmates. The band then became known as "Operation: Mindcrime." After releasing three studio albums, Operation: Mindcrime disbanded in 2017. In addition to his work with other bands, Tate has also released two solo studio albums: a self-titled album in 2002 and "Kings and Thieves" in 2012.
