Since 1979 Ugoletti's music has been performed by soloists such as Georg Mönch, Ciro Scarponi, Antonio Ballista, Sandro Gorli, Giuseppe Garbarino, Claudia Antonelli, Massimiliano Damerini and Piero Bonaguri.
In 1989 Ugoletti became a professor of composition at the Conservatory "Luca Marenzio" of Brescia; at the same time he started a long-lasting collaboration with the "Sagra musicale umbra".
It commissioned works such as the Gloria of the Missa Solemnis Resurrectionis, premiered in Rome on the occasion of the Jubilee 2000 and the completion of the Lacrimosa and the composition of the Amen of Mozart's Requiem in 2002.
In the early nineties (1990–93) he dedicated himself to the study of Irish traditional music which, in the following years, inspired the composition of numerous works linked to the Celtic world and expressiveness.
Since 2000 he has been composing numerous works using soloists, choir and orchestra and inserting instruments of other musical genres: uilleann pipes, tin whistle, Celtic harp, bass and electric guitar, electronic keyboards, drums.
