Signal Quartet is a collective musical ensemble based in Southeast Michigan consisting of Ben Wolkins on Trumpet and Flugelhorn, Ian Blunden on Guitar, Eric Nachtrab on Bass and Sean Perlmutter on Drums. The group's repertoire is comprised of original compositions by members of the band which serve as springboards for far-reaching improvisations; showcasing the tight communication and shared musical vocabulary of the ensemble. The band's approach to improvisation is one of following the music wherever it leads, embracing the unexpected and the unusual, and striving for a truly new creation at each and every opportunity. Shortly after the release of the band's self-titled debut, the group was featured at the Detroit Jazz Festival and the album continues to receive radio play around Michigan and beyond. Signal Quartet's sophomore effort, “Second Exploration: the Music of Ben Wolkins” will be released in April of 2023.
