Got a chance to see Etienne Charles’ group at Dizzy’s in New York a few weeks ago. Learned a lot. The trumpeter’s role as an educator went far in aiding his descriptions of the inspirations behind his new San Jose Suite (Culture Shock). They stretched from tales of indigenous people trying to hold their own against conquistadors to the segregation travails on Cali campuses in the mid-’60s. Along the way, his sextet proved just how tight a mid-sized jazz band can be. Pliable, exploratory, animated. Highlight: the fierce alto inventions of saxophonist Bryan Hogans. Listen close to their unity, but keep a heads up as Charles ‘splaining those cultural politics.
