In 1598 he joined the court of Duke Vincent I in Mantua, and probably served the Gonzaga family the rest of his life, with whom he travelled all over Italy and as far afield as Poland.
In 1607 he created the title role in Claudio Monteverdi's Orfeo, and in 1608 sang in the first performances of Marco da Gagliano's La Dafne.
[1] In 1610 in Tuscany Rasi and his accomplices were sentenced to be hanged, drawn, and quartered for the murder of his stepmother's servant and the attempted murder of his stepmother; however because of the protection of the Gonzaga family he escaped, and his sentence was eventually annulled with the agreement that he never return to Arezzo, his birthplace.
[1] He wrote an opera, Cibele, ed Ati, which seems not to have been performed and whose music does not survive, and another libretto, Elvidia rapita.
[2] Rasi was a well-respected singer, whose skill in ornamentation and diminution, beautiful voice, and ability to sing with grace and feeling, led to him being involved in the first performances of many of the first operas.
