Uc's only existing work is a sirventes, "De mots ricos no tem Peire Vidal", that begins with a gab proclaiming his superiority to eight of his contemporary troubadours: Peire Vidal, Albertet de Sestaro, Perdigon, and Aimeric de Peguilhan, as well as the otherwise unknown Arnaut Romieu, Gualaubert, and Pelardit. The rest of the poem is a ferocious attack on the morals of the baronage in the manner of Marcabru. The rime, metre, and melody of the work are copied entirely from a work of Peire Vidal, "Anc no mori per amor ni per al".
