Mastodon officially kicked off their North American tour on Thursday at the Factory in Chesterfield, Missouri, marking an exciting milestone as their second show of 2025. This performance was particularly notable as the metal titans showcased their evolving lineup with a new fill-in guitarist, following the recent departure of co-founder Brent Hinds.

So, who stepped up to hold down the guitar alongside band members Troy Sanders, Bill Kelliher, and Brann Dailor during this significant performance?

The honor of filling in went to Nick Johnston, a talented Canadian musician with extensive experience in the realm of heavy progressive music. At just 37 years old, Johnston has already made a significant mark in the music industry, having released six solo albums and collaborated with prominent artists such as Intervals, Scale the Summit, Periphery, Polyphia, Paul Gilbert, and Guthrie Govan. His impressive touring history includes performances with the renowned Australian guitarist Plini, as well as touring with Between the Buried and Me and The Contortionist back in 2019. Additionally, Johnston has partnered with Schecter to create a line of signature guitars that reflect his unique style.

Johnston is following in the footsteps of Ben Eller, the popular YouTuber known for his series “This Is Why You Suck at Guitar,” who previously filled in for Mastodon during their March appearance at Tool’s Live in the Sand festival.

While Mastodon has yet to officially comment on Johnston’s involvement with the band or confirm whether he will be a long-term addition, the current tour schedule is packed with dates through August. Given this timeline, it seems unlikely that the band would seek out a third guitarist, indicating that Johnston may be settling into this role for the foreseeable future.
