John Preston Solinger was an American singer known for being the lead vocalist of the hard rock/heavy metal band Skid Row from 1999 to 2015.

United World Rebellion is a duo of extended plays from the American heavy metal band Skid Row. The first and second chapters were released on April 16, 2013, and August 5, 2014, by Megaforce Records and were Skid Row's final recordings with singer Johnny Solinger. A third chapter was planned and scheduled for a 2015 release but was pushed back to 2016 due to Solinger's departure and pushed back again due to Tony Harnell's sudden departure. The third installment was planned to feature ex-DragonForce lead singer ZP Theart, but he was later replaced by Erik Grönwall. The third chapter was ultimately scrapped with the band's next record having the title The Gang's All Here instead.
