Gabriel Szternsztejn was born in Buenos Aires, Argentina, in 1968. His compositions feature a blend of diverse music styles, such as Jazz, Tango, Latin American Folk music and contemporary harmonies and rhythms. With a mainly acoustic sound, and having the guitar as main overall voice, improvisation still retains an important place in his work.

He attended the Collegium Musicum and the National Music Conservatory «Carlos Lopez Buchardo»; he took guitar lessons with great names such as Vicente Elias, Graciela Pomponio, Sergio Moldavsky and Fernando Egozcue. He also studied Improvisation and Jazz Harmony, as a private student of Pino Marrone and Javier Cohen and attended seminars with Pat Metheny, John Scofield, Mike Stern, Scott Henderson, Joe Diorio, Ralph Towner and Egberto Gismonti.

As a session player, he worked with Chico Novarro, Andrea Tenuta, Pino Solanas and Tato Bores, plus countless recording sessions for TV and film soundtracks for Raul Parentella, Ivan Wyszogrod and Juan Blas Caballero, among others. He has also composed, recorded and produced the soundtracks of several movies like: «Monoblock 26» by Ezequiel Groisman; «Lejania», «Una vez, una tarde», «El compartimiento», the three of them by Leonora Kievsky.

For the past ten years, he has developed a keen interest in teaching, doing so at music academies such as «Tademus» and «T.E.M.A.», both in Buenos Aires, and «Arión», «Escuela de Nuevas Músicas», «Musical Sur», «Escuela de Música del Ayuntamiento de Coslada», «El Almaden», «Escuela de Música Creativa» all of them in Madrid. He also gives private lessons.

In 2001 the Argentinean label PAI edited Gabriel's first solo album. The featured guest musicians are a line-up of the highly reputed players in Argentina's creative music scene.

In Spain, where he currently lives, he is playing his music with his own quartet. He has also played for «Vida y Muerte de Pier Paolo Pasolini», a play directed by Roberto Cerdá, and is a member of bossa nova quartet «Insensatez», «Juan Esteban Cuacci Quintet» and is playing together the Argentinian singer María Lavalle Band.
