The singer’s ex-bandmates memorialized him in a Facebook post on Saturday , the day he died.
Solinger revealed his liver failure diagnosis on social media last month.
The rocker further explained that he was taking at least seven different medications, getting his abdomen drained of fluid every few days and undergoing physical therapy.
Solinger joined a newly reformed Skid Row in 1999, taking the place of Bach, who left the group in 1996, the same year they broke up.
Solinger left Skid Row in 2015; his position was filled briefly by TNT singer Tony Harnell and then by ex-DragonForce frontman ZP Theart, who currently fronts the group.
