PD9 is a pared down version of the traditional big bands of the 1930s, and they frequently feature guest vocalists, adding to the versatility of the band's show. The number of musicians in the lineup is reminiscent of the earliest big bands, when swing was still evolving into the sound that defined jazz music's most popular era.

If you have not yet experienced Planet D Nonet, your groove tank is missing out on some serious fuel.  

They're Detroit's own down and dirty little big band, known nationally for curating some of the best in early jazz traditions and Black-American musical influences from the 20s, 30s and 40s. More "hot" than "sweet," according to PD9 cofounder and bandleader RJ Spangler, who started the nine piece ensemble with longtime musical partner James O'Donnell in 2007.
