KeyBank Live at Larkin presents Grosh Prime featuring Alex McArthur, Harry Graser and Zak Ward

Grosh is a genre-blending powerhouse that effortlessly melds hard rock, blues, and funk into a unique sonic experience. Returning to this season-closing spot, they’ll again become Grosh Prime, featuring ringers Alex McArthur (vocals, keyboard), Zak Ward (vocals, guitar) and Harry Graser (keyboards), to put a proper exclamation point at the end of another fun summer of free concerts in Larkin Square!
