Fabio Alessi's musical experience is wide-ranging. After piano diploma, Fabio started his musical career as a classical pianist. He won several prizes in italian piano competitions - Stresa, Albenga, Macugnaga and Savona contests - and till 1992 performed as a soloist or with chamber groups. After 1992 he shifted his interests. He started studying and playing double bass. This over decade's experience led him to better understand the pop/jazz world and merge his classical background with different musical perspectives, techniques and approaches. On the other hand, he indulged his old passion for a cappella music: in 1997 he founded and had been singer, leader and arranger of the italian a cappella group Mezzo Sotto. Mezzo Sotto, with their jazz/pop repertoire, concerts all over Italy and abroad and three published albums, had been appreciated as one of the finest italian a cappella groups. During the fifteen years with Mezzo Sotto (now retired), Fabio's name began to spread as an a cappella arranger, whence he began collaborating with several a cappella groups. Some of his collaborations with a cappella ensemble: Alti & Bassi, Ardú, L'una e cinque, Penthelia Singers, Perpetuum Jazzile, Ring Around Quartet, Vocalica.
At the present time Fabio sings with the italian a cappella group Vocal Cocktail, and continues arranging a cappella: he has produced about one hundred arrangements and some original compositions (some of his charts were published by Edizioni Preludio and Edizioni Paoline). His current position is associate professor at Udine University, Italy. Since March 2015 he is the director of the Udine University Choir.
