"The Complete Marches of John Philip Sousa" is a multi-year recording project and is the Marine Band's first comprehensive collection of Sousa's marches since the 1970s. Initiated by Director Col. Jason K. Fettig, the collection is presented in chronological order. Volume 1, released on April 6, 2015, contains Sousa's first 17 marches, covering the years 1873 to 1882. Volume 2, released on April 11, 2016, contains 18 marches, spanning the years 1883 to 1889, when Sousa was Director of the Marine Band. Volume 3, released Dec. 12, 2016, includes 20 marches Sousa composed from 1889-98. Volume 4, released April 9, 2018, includes 20 marches Sousa composed from 1899-1916.
The volumes are available for free download exclusively on the Marine Band website, along with scrolling videos and PDFs of the full scores that include historical and editorial notes about each piece. Each march has been carefully edited and corrected by Col. Fettig and Music Production Chief Master Gunnery Sgt. Donald Patterson using some of the earliest known publications and incorporate performance practices employed by the Marine Band that are modeled on those of "The March King" himself.
