Hiroshi Kono, a native of Nagoya, Japan was determined at 12 years of age to play rock 'n roll and switched from acoustic to the electric guitar to form a band. As the result of playing in various bands, he commenced original compositions at 15. Determined to play in the U.S., he reached his aspirations and moved to New York in 1992.

Upon arriving, he joined the Spectres, an American rock'n roll band. The Spectres played hundreds of gigs and recorded with Peter Denenberg, (known as the producer of the Spin Doctors) but disbanded in 1994.

After the participation in the rock band, "Remember Alice?" in 1995, he made a 5-track CD, "Les Duex / Polen D'hiro," with his former bandmate, Paolo Frassanito, in 1998. Shortly afterward, however, he realized that he would need to find a way to grow as a musician.

In the wake of this crossroads, he started taking classical guitar lessons with music professor, Lars Frandsen, thus, causing his musical exploration to turn 180 degrees from rock to opera, classical, ballet and world music.

Via the exposure to various styles of music, he created original composions - singing with the classical guitar. Thus, he concluded he discovered the music he had been searching for and, consequently, founded Mar Project in 2001.

In 2002, Hiroshi wrote some music for Wilson Loria's monologue, 'To The Winners' , which was released in June, 2003.

After completion of Mar Project's first album, "Mar Project I" in 2004, he continues to creating new music and ha s recently finished MP's 2nd album, "Stepping Stone/Mar Project," which was released in September, 2007. He also contributed a piece of music to Wilson's new piece, "ões".
