Born in Milan, Italy, Marco developed a passion for music at a young age. He received his first guitar as a gift, at age 9, when he was enrolled into the Lainate Private School in Milan. While there, he studied both classical and contemporary music and was influenced by a variety of classical and modern artists. At age 17, he was introduced to the fire of flamenco jazz, as played by Al Di Meola, John McLaughlin, and Paco De Lucia, and to the passionate tango music of Astor Piazzola. By age 21, Marco was composing.
Marco describes his music as being characterized by having the techno-structural complexity of classical music and the expressive spontaneity of improvisation.
In 1993, he founded "Altus Karma," together, with the virtuoso bassist Alberto Viano. Altus Karma performed with a latino feel and virtuoso elegance. In the summer of the same year, they performed a series of concerts at S. Anna Arresi Province in Calgiari, Italy, alongside the Gipsy Kings; The Orroli Festival, Nuoro, which included such international artists as Farafina and Al Copley; and the S. Anna Arresi Jazz Festival, hosting such artists as Al Di Meola, Paco De Lucia, Tim Berne, Kenny Garret, and Manitas De Plata.
In 1995, Marco released the CD "Altus Karma." In 1996, he founded "Diatribra," together, with Flaviano Braga on accordion, Giovanni Giorgi on drums, and Roberto Bernardinello on bass. In the same year, they participated in "Al Confini Tra Sardegna e Jazz," opening for Noa. The festival also included other international artists, such as Herbie Hancock, Michel Petrucciani, and Pat Metheny.
In 1998, Marco began collaboration with Giovanni Prosdocimi and Fracesco Loi, forming "Marco Porcu & M.C.M. Ensemble." In 2000, on the 25th anniversary of the Saridinian television station "Videolina," he performed with the group "M.C.M. Ensemble."
In 2003, Marco continued to work in collaboration with "Videolina." He has recently been collaborating with Roberto Bernardinello, performing in London, Kansas, and California as MP Project. Marco was recently honored as recipient of the 2005 Artist in Residence Award by the Wichita Guitar Society.
