This is the second CD which, along with Jazz Sebastian Bach, are the rereleases of the early Les Swingle Singers who were a world renown phenomena. Ward Swingle's original intent had been to sing exact vocal versions of big band classics. All of the original octet had been classically trained musicians, most with perfect pitch. They sang Bach merely for practice to improve their sight reading and musicianship.The idea of 'swinging it' (jazzing it up) came later after the bass and drums were added. This fortuitous evolution leaves us with a wonderful compilation of "Swingleized" works by Mozart, Handel, Vivaldi and Bach, mostly Mozart's and Bach's work.
