“Rignin’ and Swingin’” features an extensive repertoire of fun, swinging classics by jazz and pop legends, with intricate arrangements and vocals seasoned by the George Maurer Group’s famous lighthearted flair. Just when you expect them to pull another jazz riff out of Santa’s bag, they might give you a little hint of Led Zepplin instead. Just when you least expect it, they might take you on a nostalgic journey to Christmases’ past with a heartfelt rendition of a time-honored favorite.
