These accompanied songs were recorded in the early 1930's, when the Boswell Sisters enjoyed a devoted following - unexpected, given that they were three classically-trained women singing New Orleans blues-flavored jazz! This recording's quality, incidentally, is very good, with every attempt to preserve the integrity of the original analog masters, but using today's digital technology for clarity. The CD's opening track, "Rock and Roll," though having nothing to do with its current meaning, shows that the term predated Alan Freed by over twenty years! Uptempo numbers, such as "Louisiana Hayride," with its swerving instrumental break and riffing clarinet, are interspersed with ballads, such as Ellington's "Sophisticated Lady," and "Song Of Surrender," from the film Moulin Rouge. The Boswells close harmony sound is much more blues than classically oriented - not refined or shrill, but punchy and full.
