The Brink (Shiny Boy, 2023) is Leppin's first solo cello recording and was performed live without overdubs. An album for voice and cello called
American God was released in April 2017. This album continues with political themes, as Leppin composed it with the
2016 presidential election in mind. In April 2016, Leppin released two solo recordings;
Mellow Diamond and
Songs for Voice and Mellotron. Originally titled "Songs of the One-Armed Woman",
Songs for Voice and Mellotron was written in 2015, when Leppin injured her right elbow and was unable to perform solo concerts on her primary instrument, the cello. The
EP-length recording includes politically-charged music. Most tracks were recorded live with Leppin singing and playing the M4000D mellotron simultaneously, with little overdubbing. Leppin's first solo recording,
Mellow Diamond, draws from various genres including avant-garde pop and ambient music. She recorded vocals, analog synthesizers,
harpsichord, pedal steel, cello,
mellotron,
found sound samples, and
radio frequencies. Several political messages are found in the work. Music critic Roger Trenwith wrote
"Art Holds Her Hand, a funereal paced and sombre death march, atop which Janel’s lilting ice maiden tones lull us into the land of Morpheus with impressionistic tales of the primal forces of Nature." Lars Gotrich of NPR Music, in regards to Leppin, wrote "instrumental intimacy swept up in arrangements that cluster around her voice, as delicate and as imposing as a sheet of falling ice.” ==Jazz works==
