There's nothing to explain here, really. “Rock Soldiers” is an old hard rock anthem from the first self-titled album of the band Frehley's Comet formed basically to start the solo career of none other than Mr. Ace fucking Frehley! The song is just brilliant, Ace still plays it live on every tour and you gotta hear how freaking loud the crowd yells “Ace is back and I told you so!” and “He's gotta play without ace in his deck!” parts!
The part is simple yet catchy and I'd definitely recommend this song to any beginner, just to work on timing and have some fun!
