Trumpeter Erik Jekabson and drummer John Santos are North Bay institutions, each of whom has a loyal following and a career of exciting collaborations and experimental projects. This week, the two team up for a special afternoon concert that will explore diverse and engaging jazz. Jekabson’s quartet makes smart, post-bop jazz that’s both melodic and avant-garde. Santos is known for his Afro-Latin-jazz fusions and sharp drumming. Together, the two will push the boundaries of their talents for a day of music presented by the Napa Valley Jazz Society. The Erik Jekabson Quartet and John Santos perform on Sunday, June 15, at Silo’s, 530 Main St., Napa. 4pm. $20—$40. 707.251.5833.
