In his early teens, Pearcy aspired to be a top fuel race car driver[clarification needed] and expressed no desire to pursue a career in music.

In 1996, Pearcy dabbled in an industrial metal band called Vertex (with Megadeth's Al Pitrelli and drummer / electronic producer Hiro Kuretani).

Pearcy rejoined Ratt in 2006[5] before leaving again on April 24, 2014, explaining he was "officially done with having anything to do with them due to the constant turmoil, unresolved business, personal attacks/threats in the public forum, and most of all, the disrespect to the fans".

[8][9] A new Ratt lineup including Jordan Ziff (lead guitars) and drummer Pete Holmes (from the band Black and Blue) performed a handful of shows in late 2018 and embarked on a world tour starting in May 2019.

The latest, "View to a Thrill", was released on Frontiers Music/Top Fuel Records in November 2018; the music from the album was written by Pearcy and guitarist Erik Ferentinos.

Pearcy underwent knee replacement surgery in 2019, three months after two Ratt shows that saw him incapacitated to the point where he had difficulty remembering the words to some of the band's songs.
