Former Queensryche frontman Geoff Tate is auctioning off a stage set to raise medical funds for a fan who is still recovering from a brutal attack outside Dodgers Stadium in Los Angeles on opening day of the baseball season in 2011.

San Francisco Giants fan Bryan Stow was beaten unconscious by two thugs who are currently serving jail sentences for their actions. He sustained severe injuries to his brain and was placed in a medically-induced coma after the incident.

Tate and his Queensryche bandmates visited him in hospital after learning he was also a huge fan of the group, and now the rocker is hoping his backdrop will help raise money to aid Stow's family cover his rising medical costs.

Tate says, "We were incredibly inspired by his love for life, his love for his family and his love for our music."

The stage set will be put up for auction on on Sunday (31Aug14), the day after Tate's final Queensryche gig - as part of a settlement following his departure from the band last year (13), he was allowed to tour under the band's name until the beginning of September (14).

Tate, who will become the frontman of Operation: Mindcrime from next month (Sep14), says, "It's (backdrop) truly a special part of our musical history and we'd like to raise some much-needed funds for Bryan so he can continue his progress.

"We're honoured and thankful to have fans like Bryan in our life and would like to present him with a cheque just prior to Thanksgiving (27Nov14). Every little bit helps at this point and we hope to continue our efforts for Bryan and his family down the road."
