Sandro Orrù, aka DJ Gruff, undisputed protagonist of the Italian hip hop scene since its origins, meets Gavino Murgia for the project “On the Waves of Marconi” by Gavino Murgia. The multi-instrumentalist Gavino Murgia (soprano, tenor and baritone sax, flutes, duduk, launeddas and tenor singing) is a composer whose path is deeply influenced by his Sardinian musical roots. The singing of Tenor in the role of Bassu and the traditional study of launeddas, merge over time with African-American music, finding a new and original path.
