The collective Tetraurum emerges from the union of a group of friends, musicians, and students from the Professional Jazz Instrumentalist Course at the Escola Artística do Conservatório de Música de Coimbra. Together, they explore a broad and eclectic repertoire, drawing on various jazz idioms, from bebop to avant-garde. This quintet of young musicians consists of Jasmim Pinto on trumpet, Rodrigo Octávio on tenor saxophone, Francisco Ribeiro on electric guitar, Ana Gomes on electric bass, and Tiago Gaspar on drums.
