Index debut spotlights difficult-to-express feelings, bringing out friction between dreamy hooks and harsher sonics. Written like a DJ set, the album shifts between piano-led trip-hop, lounge, dream pop, 2-step, and breakbeat house.

On her first Harmony Index album, multi-instrumentalist and producer Nico Leibman spotlights the feelings that are most difficult to express, bringing out the friction between her dreamy hooks and harsher sonics. Written almost like a DJ set, the album shifts intentionally between piano-led trip-hop, lounge, dream pop, 2-step and breakbeat house, not languishing in nostalgia but defining a language that's rooted in desire, surrender and forward motion.

Until now, Leibman has been best known as a touring musician, working alongside artists like Jessica Pratt and Ana Roxanne, while slowly putting together new solo material in-between frequent tours. The album was written in bursts over the course of five long years and provided Leibman with a much-needed outlet - a chance for her to lock into her personal musical preoccupations, like Janet Jackson's 'The Velvet Rope', Everything but the Girl's 'Walking Wounded' and Prefab Sprout's 'Jordan: The Comeback'.

It's this era of pop - when nascent technology collided at force with skillful, soulful songwriting - that provides the album's backbone, fleshed out by Leibman's potent meditations on a spectrum of experiences in Los Angeles. And as the record was evolving, Leibman let long night drives crack her creative world open. Embracing the city's notoriously cinematic romantic side, she used the car as a "little chamber of limerence," in her own words, enabling her fantasies and acting as a test system for each song. "If it wasn't hitting in the car," she says. "It wasn't going to be on the record, period."

This sense of motion is evident almost immediately on 'Recognize', when Leibman's breathy words are carried into the night by choppy, uptempo breaks and resonant pads. So even when she simply coos over chugging guitars and bass on the first half of 'Enough', the drop into a low-slung breakbeat is implied. "Another digression, a break in this tension," she sings. "Was I foolish to believe that this was never your intention?" Leibman's tales of disillusionment are imbued with power, buoyed by her pitch-perfect production, with additional help from co-producer Cesar Maria.

On 'Don't Pretend', she sings softly and soulfully over decelerated Timbaland-inspired beats and a dubwise bassline, aided by additional production from Purelink. And 'If' marks the point where she lets go, infusing her euphoria with melancholy as her voice soars alongside the album's most infectious piano riff. Fittingly, the album concludes with 'Trust', a song about surrendering to the possibilities of love that works as a potent metaphor for the album's evolution. Over the course of five years, Leibman learned to let people in, finally trusting the process. "It's also a fantasy of what it would feel like to finally be in love again," she laughs, accepting that it's still just a fantasy. But it's this hope in unfulfilled longing that gives the album its unique character, defining a bold, unguarded voice in LA's experimental pop landscape.
