Steven Adler of Guns N’ Roses lineup: Michael Thomas, AJ, Cristian Sturba, Ari Kamin. 

Steven Adler was fired from Guns N' Roses over his heroin addiction in 1990, following which he reformed his pre-Guns N' Roses band Road Crew and briefly joined BulletBoys. During the 2000s, Adler was the drummer of the band Adler's Appetite, and from 2012, he had held the same position in the band Adler. In early 2017, he declared that he had no intention to continue with the band and that the band has been dissolved, with the reason being his lack of interest in performing during poorly attended concerts.
