On March 21, 2026, the band announced that drummer Tosh Peterson had joined the band as Willard’s replacement. In a statement on Instagram, Skiba wrote: “I met Tosh at Swingers a few months back for lunch, to meet up and discuss the possibility of him playing in Alkaline Trio. Tosh’s mom was also there, who turned out to be a fellow history buff so her and I spent half the lunch talking about Churchill and the Miracle of Dunkirk while Tosh politely ate his fries. He later told Dan that if we had had a problem with his mom coming to lunch he probably didn’t want to play with us anyway. Apart from the absolute MONSTER he is behind a drum kit he is just a lovely guy: KIND, polite, enthusiastic, driven and HILARIOUS. I told Dan I wouldn’t want Tosh to play with us if he HADN’T brought his mom. Tosh is a beautiful human being we’re very excited to travel and play music with and a drummer we couldn’t be more thankful to be able to welcome into OUR family.” Alongside his forthcoming work with Alkaline Trio, Peterson is Lady Gaga ‘s live drummer, and he has performed and toured with Troye Sivan , Filter , Fall Out Boy , Machine Gun Kelly and Lil Nas X , amongst others.
