The biography captures the freshness and ingenuity of the project [of Carlos's Switched-On Bach].

... the first serious book to examine Carlos’s legacy at length, both as a composer and as a transgender woman. It’s an essential read—not only for electronic music fans, but for anyone interested in the history of gender and popular culture.

... [a] fine new book.

... noteworthy in that it manages to be primarily about Carlos the composer, the musician, the vanguard of electronic music. While her gender identity is certainly written about in great length, it's never approached as a morbid curiosity. If anything, it's used primarily to chronicle the challenges Carlos encountered around society's preconceptions and prejudices toward transgendered people.

Even with limited secondary sources to rely on, Sewell has written a long-overdue scholarly work that sheds light on Carlos’s creative process while never sensationalizing her private life.

Sewell focuses more on Carlos’ music than on her personal life, as Carlos would clearly wish, though she didn’t participate in this book or consent to an interview. Nonetheless, the author demonstrates that she was as important to the success of the Moog synthesizer as the Moog was for her, that she was a pioneering artist in ambient music as well, and that she dismissed being pigeonholed for her synthesized Bach.
