Javier Hernando's musical journey began in 1979 with his first band, Xeerox. In 1981, he embarked on his first fully electronic project, Melodinamika Sensor, which continued until 1985. During that year, three tracks by M.S. were featured on a compilation LP titled Grupos de Barcelona, released by Discos Esplendor Geométrico. This compilation showcased four bands from the thriving Barcelona underground scene. From 1985 to the early nineties, Hernando co-directed the cassette label Ortega y Cassette, while also hosting Los Silencios de la Radio on Radio PICA. This radio program was dedicated to showcasing electronic and experimental music. In the nineties, he released new works in cassette format, including two albums on Toracic Tapes, and later published the CD Luz Nacarina through Geometrik Records.

Subsequent releases took listeners on a journey through post-industrial landscapes, interspersed with moments of serene tranquility. These releases gained notable recognition from Geometrik, as well as other respected labels such as Alku, con-v, Nostalgie de la Boue, Anòmia, Novak, and República Ibérica Ruidista. More recent works have revealed a shift towards harmonious compositions, evident in albums like Jardín Náufrago released on La Olla Express. Hernando has also explored poetic atmospheres in collaborations such as the CD-book El Archipiélago Sideral with artist Juan Miguel Muñoz, and Vacuola, his latest release on WD Records, in collaboration with Ángel Lalinde. Currently, Hernando's artistic trajectory is at its most vibrant and creative state. The highly anticipated album Dómina Esteléctrica is set to be followed by a new composition that transcends the hermeticism of painter José Manuel de Yngunza, as well as a collaborative work with Krishna Goineau (Liaisons Dangereuses, Velodrome). These upcoming projects promise to further expand Hernando's artistic horizons and captivate audiences with his innovative approach to music.
