This summer, I'm teaching several lecture/demonstration classes on The Beatles, including a five-class course called "The Beatles in Their Prime: Rubber Soul, Revolver and Sgt. Pepper," at the University of Pittsburgh's Osher Lifelong Learning Institute, main campus. While this course is open only to Osher students, I'll also be teaching a two-hour course focusing on "Revolver" (released August 5, 1966) at Cooper-Siegel Library, Fox Chapel, Sunday, Sept. 11, 2 p.m. It was 50 years ago today (more or less) that these three albums first rocked the world, and they still sound catchy, innovative and even profound. Come and glean some new insights into the fascinating details of how this music was made.
