After an eight-year hiatus, The Great Spy Experiment made its comeback with a fourth appearance at Baybeats on 8 Oct 2023 at Powerhouse² (Singtel Waterfront Theatre at Esplanade). Armed with a repertoire of crowd favourites, the band brings their distinct brand of emotive and powerful indie rock to the venue that has been their spiritual home, with the goal to move the hearts of fans once again.

Formed in 2006, The Great Spy Experiment is considered to be one of Singapore's indie rock veterans. Effortlessly blending elements of indie rock, pop, and dance-electronica, the band's music is as much guitar-led as it is beat-driven, with indie riffs juxtaposing melodies that tug the heartstrings—music created with the dance floor in mind and bedroom at heart.

The band has released two albums, Flower Show Riots in 2007 and Litmus in 2013, with Litmus making history as the first in Singapore to break through iTunes album charts. Prior to their hiatus, The Great Spy Experiment delivered electrifying live performances touring across the world and was the first homegrown band to play at SXSW Festival in 2007. With their innovative sound and charismatic stage presence, they have earned a dedicated following, making them one of the leaders of Singapore's independent music scene. After disbanding in 2015 and a lengthy hiatus, The Great Spy Experiment returned with a new release Sanctuary/Secrets, a two-track single embodying their signature sound—powerful yet poignant.
