Quatuor Bozzini, in Montréal, is one of the leading contemporary music ensembles, and a frequent collaborator with Lucier. As Isabelle Bozzini, a founding member of the quartet, describes, in the winter of 2020, Lucier asked if they would release the live recording of a 2015 concert of his music. Instead, the quartet decided to make an entirely new album. Bringing together echolocation ideas (there are two performances of Group Tapper) with explorations of frequencies in concert and conflict (Navigations), Navigations is a superb way to hear Lucier as he expands out of the Western art music tradition.
