Though the musical universe of guitarist Ben Monder is vast, the paths to his aural galaxies are rather solitary and arduous. It takes considerable time for Monder to create his unique, mind-bending recordings, as the practice, sculpting, and arranging can take years. His latest recording, Planetarium, is a prodigious piece of art that showcases the widest breadth of his vision as a composer and craftsman. Monder is well known for his tremendous guitar contributions to a wide range of artists, including David Bowie, Maria Schneider, Guillermo Klein, and, most recently, as a member of The Bad Plus. Though he may be most celebrated for these contributions, his own projects deserve equal attention, as they are personal, large-scale works utilizing a select coterie of trusted associates. Planetarium's inception began in 2014 when Monder was awarded a grant from The Shifting Foundation to write and record an album. While that project ultimately took a different direction, work on this one would continue for the next ten years. The effort was thrust into high gear when the pandemic hit, as there were few distractions to composing and practicing. During this time, Monder also received a commission to compose what would become the ambitious piece, "Ataraxia."A most helpful association for Monder has been with engineer and producer Joseph Branciforte, whose Greyfade Studio in Mount Vernon, New York became a sort of second home for him during the recording process. Beginning in December of 2020, the two began to meet frequently at the studio, setting down ideas and inviting collaborators to add their unique contributions. These integral guests included drummers Ted Poor and Satoshi Takeishi, bassist Chris Tordini, and vocalists Theo Bleckmann, Charlotte Mundy, and Emily Hurst. After three years of recording, Monder produced his grandest statement yet as a composer and conceptualist. This three-disc set features vast, highly wrought sound poems as well as spontaneous moments of improvisational brilliance.
