Almost every week from the second Sunday of September through Pentecost, which this year is June 4, the Westminster Presbyterian Church holds a 50-minute Jazz Vespers service. The 4 p.m. service at the church on West Moss Avenue consists of a “small combo in jazz standards and original compositions” and is led by David Hoffman, who was the trumpet/flugelhorn soloist and composer/arranger with the Ray Charles Orchestra for 15 years.
