This disc is full of discoveries, including Martinu's Fantasia, and Grainger's graphically notated Free Music #1, along with other "period" works by Schillinger (known for his writings on music and as a guru to composers from Gershwin to Earle Brown) and Isidor Achron (the accompanist to Heifetz). Modern works are represented by Kavina herself, Brazilian Jorge Antunes (with electronic tape) and Russian Vladimir Komarov, whose work also incorporates the inventor's voice and a rendition of Glinka's infamous The Lark, which Theremin had performed for Lenin to demonstrate the instrument.

Lydia Kavina is today's leading thereminist. The granddaughter of Leon Theremin's first cousin, she was the inventor's last protégée. She began studying the instrument with him at the age of 9, and was concertizing by age 14. She has appeared in Howard Shore's soundtracks to eXistenZ and the Oscar-winning movie Ed Wood, and has performed in the Tom Waits/Robert Wilson collaborations Alice and The Black Rider. Kavina now serves on the lecture staff of The Glinka Museum and is affiliated with the Theremin Center, both in Moscow. Kavina is accompanied by pianist Joshua Pierce (noted for his series of Cage piano works on Wergo as well as a virtuoso performer in the Romantic repertoire), the renowned Portland String Quartet and coloratura soprano Elizabeth Parcells.

A second disc of theremin works with Lydia Kavina and chamber ensemble by Oscar winner Howard Shore, Olga Neuwirth (one of Europe's leading contemporary composers), Christian Wolff, Percy Grainger and Miklos Rozsa's Spellbound. For release in 2006.
