Richard Vacca describes Boston in the early 20th Century as "an incubator of musical talent, a training ground for jazz journalists, a magnet for music education and a proving ground for new approaches in jazz presentation." With that, he aligns the city, and the South End in particular, with New Orleans, Chicago, Kansas and New York City. Black musicians had their own union here as early as 1915. Impressario Charlie Shribman booked musicians up and down the Northeast seaboard since the 1920s. And while a Boston musician always kept a bag packed for "the call" from New York City, the deep talent pool that emerged locally also kept a core group of music veterans that seeded venues like the Savoy Cafe, the Hi-Hat, the Pioneer Social Club and Wally's. The author said in a recent phone conversation that the time frame of his book, the late 1930s to the early 1960s, is a "curiously neglected bit of historical scholarship." He explained that Boston's reported history tends to go from the 18th and 19th centuries straight into the Boston busing crisis, with little in-between. His meticulously researched and fluently written history of the Boston jazz scene will be the subject of Vacca's talk and slide show on Tuesday, February 18, starting at 6:00 PM. His book, The Boston Jazz Chronicles: Faces, Places, and Nightlife 1937-1962, will be available for sale and borrowing. Refreshments will be served. The South End library is fully handicapped accessible.
