Mason Hill formed in Glasgow around guitarist James Bird and vocalist Scott Taylor, later solidifying into a five-piece with Marc Montgomery, Matthew Ward, and Craig McFetridge. The band's sound is modern hard rock built around large choruses, thick guitar riffs, and a polished but forceful production style that draws from post-grunge, alternative metal, and classic arena-minded hard rock. Their self-titled 2015 EP introduced the group's melodic but heavy approach, and years of UK touring helped them build a dedicated following before the release of Against the Wall. That debut album, released in 2021, turned the band into one of the more visible new Scottish hard rock acts, driven by songs such as "D.N.A.," "Find My Way," "Hold On," and "Against the Wall." After Taylor's departure, Mason Hill returned with Tom Ward on vocals, keeping the band's guitar-centered identity while opening a new chapter. Their music remains focused on resilient, high-impact rock songs: tight rhythm work, muscular riffs, emotional vocal hooks, and a live sound designed for bigger rooms.
