Amber Mark Drops “Sweet Serotonin” and Announces Fall Tour with Sabrina Carpenter

Amber Mark’s “Sweet Serotonin” teases new album and aligns with fall tour dates across North America.

Amber Mark brings her signature blend of soulful finesse and lyrical clarity to “Sweet Serotonin,” the first single from her forthcoming second album. Released via PMR / Interscope Records, the track marks a return to more emotionally driven songwriting and a departure from the club-ready sounds of her Loosies EP.

There’s a relaxed charm to the track, underscored by warm instrumentation and Mark’s poised delivery. She opens with: “I’ll say this really clear now: Yeah, I want you, baby,” signaling a tone that is direct and emotionally open.

“You talking sweet, you talking sly now / You giving me that sugar high now,” she sings, weaving through the melody with effortless control. Each line resonates with sensual rhythm and intentional intimacy.

Following her appearances at BST Hyde Park in London alongside Sabrina Carpenter, Mark is set to support Carpenter on her Short n’ Sweet tour this fall. The run includes five nights at Madison Square Garden and six shows at Crypto.com Arena in Los Angeles, with additional dates in Toronto, Nashville, and Pittsburgh.

“Sweet Serotonin” showcases Amber’s evolution into a more nuanced storyteller — one whose music doesn’t rush but rather lingers with intention and meaning.
