Guillermo Carlos Cazenave (born September 18, 1955) is an Argentine musician who has been living in Europe for more than four decades, in London, Sitges (Barcelona) and near Collioure (Southern France).

A while later they returned to Argentina with the first albums by the Beatles, and Guillermo, after seeing the band The Dave Clark Five on television, started playing the drums in 1965, later to study with the drummer and percussionist Sam Lerman.

In 1969, Guillermo started his first pop band with two classmates from the Colegio Cardenal Newman in Buenos Aires, making his debut with a performance at a party, in September of the same year.

In 2007, after an impasse of several years, he reappeared with his album Ser, and with the novel "La Noche del Grial" ("The Night of the Grail"), with prologues by Jean-Luc Robin and Javier Sierra, in which he narrates his experiences in that area.

Among greatest hits and classics of all times, like Wonderful World by Louis Armstrong, Imagine by John Lennon and unforgettable songs by U2, Rolling Stones and other English-speaking countries, they selected "Fly High" (Vuela Alto) by the musician Guillermo Cazenave, composed in 1996 for his album "Here" (Aquí).
