At Nublu, guitarist and composer Joel Harrison brings his Alternative Guitar Summit 2026 into a downtown room with a long history of boundary-testing jazz. The program foregrounds the guitar as an ensemble voice, moving between written structures and open improvisation with featured performers including Harrison and the Don’t Forget Your Guitar album-release set. In New York, where guitar-led jazz is often treated as a side current, this series argues for it as a central language. The earned point is simple: the night treats timbre and restraint as compositional tools, not decoration.
