New York-based singer-songwriter Leah Sinclair is introducing herself with Lock & Key, a debut EP that blends orchestral textures, drum & bass, shimmering synths, and deeply personal songwriting. Arriving August 21, the project establishes a distinctive musical identity shaped by everything from classical strings and ballet to contemporary pop and electronic music.
“With her debut single ‘Aries Venus,’ New York-based singer-songwriter Leah Sinclair arrives with a clear sense of identity,” wrote Reverie Magazine, while V13 praised the EP as “musically adventurous and diverse,” noting a versatility that is uncommon for an artist releasing her first major body of work.
For Sinclair, the musical language of Lock & Key begins long before she started writing songs. Although she grew up in a family of scientists, music was always the world she instinctively gravitated toward. Her parents’ record collection provided an early soundtrack, while years spent as a ballet dancer introduced her to the emotional power of orchestral composition.
Her grandmother, a classically trained musician, became another important influence, instilling in Sinclair a lasting connection to strings. That relationship with orchestral instrumentation runs throughout Lock & Key, where sweeping string arrangements meet the rhythmic intensity of drum & bass and the atmospheric glow of modern synth production.
After establishing herself in New York City, Sinclair began turning a lifelong desire to perform into something tangible. Vocal lessons and open mics eventually led to original songwriting, but there was one problem: she had been writing songs and lyrics for years without knowing how to produce them.
That changed when she picked up an omnichord and began composing from her bedroom. She eventually teamed up with fellow artist and friend Tarune, who helped bring those early ideas into fully realized productions.
The resulting EP moves freely between contrasting moods and textures. Orchestral strings weave through electronic percussion, while shimmering synths create moments that feel simultaneously intimate and expansive. The project draws inspiration from artists as varied as Lana Del Rey and PinkPantheress, alongside the fantastical world of Final Fantasy, creating a sound that refuses to sit comfortably within a single genre.
Yet beneath the production, Lock & Key is ultimately about the things Sinclair struggled to say aloud.
The EP explores desire, uncertainty, complicated connection, and the strange grief that can accompany a situationship. Rather than relying on abstract storytelling, Sinclair pulls directly from personal memories, turning intimate experiences into songs that feel exposed without becoming overly polished or distant.
“Aries Venus” and “Something Better” trace the slow unraveling of a friendship that developed into a complicated romance, while “Light” and “Lock and Key” reach further into Sinclair’s past. Together, the songs form a portrait of an artist learning to translate private experiences into music and, in doing so, allowing those experiences to become something shared.
That emotional honesty is part of what gives Lock & Key its character. The project may be Sinclair’s debut, but its musical vocabulary comes from years of accumulated influences — from her grandmother’s strings and the orchestral world of ballet to bedroom experimentation, contemporary electronic production, and the songwriting traditions of modern pop.
With Lock & Key, Leah Sinclair opens the door on a small, deeply personal world that has existed largely out of sight until now. What emerges is a debut built around vulnerability and experimentation, balancing delicate orchestration with restless electronic energy while introducing an artist with a clear sense of where she wants to go next.
