‘Sons Of Apollo consists of five greats, all of whom have earned their spurs in rock music. Billy Sheehan, bassist with David Lee Roth and founder of Mr.Big, among others. Ron 'Bumblefoot' Thal was a guitarist with Guns 'n Roses, an extremely popular hard rock band from LA. Jeff Scott Soto is a very gifted American rock singer, who is best known for the first two albums of Yngwie Malmsteen's Rising Force, but also for his short stay with the AOR rock band Journey.
