Assertion, led by musician William Goldsmith, reveals their debut album 'Intermission' out on April 9 via Spartan Records, marking Goldsmith's return to music after a decade-long hiatus. With bandmates Justin Tamminga and Bryan Gorder, Assertion's sound echoes 90's alternative rock with driving guitars, a frenetic rhythm section, and a mix of dark heaviness and delicate moments, appealing to fans of Sunny Day Real Estate and Foo Fighters.
