Tavolazzi studied cello and double bass in the Music School of Ferrara and began his career as bassist playing for Carmen Villani in a beat group, with his future collaborator, drummer Ellade Bandini. With the latter and Vince Tempera, he founded in 1969 a band called The Pleasure Machine, which released five singles in the three following years. The trio also participated in Francesco Guccini's L'isola non trovata and in Terra in bocca of I Giganti.
