Formed in 1996, Alkaline Trio embraces elements of pop, punk, and emo to create a unique sound that is hard to put into a box. Co-founded by Matt Skiba, Ron Doran, and Glenn Porter, Doran was replaced by Dan Adriano in 1997. Porter left the band in 2000 and was replaced by Mike Felumlee and then Derek Grant. Today, the band consists of Skiba and Adriano performing guitar, vocals, and bass with Grant performing mostly as a percussionist and backing vocalist. Skiba also performed with blink-182 between 2015 and 2022.
