The Big Band Arrangements Collection documents the arranging and performance career of Raymond J. (James) Greco (1921–2003), leader of the Ray Vincent Orchestra. The Ray Vincent Orchestra performed widely in the southwest Pennsylvania area, as well as in West Virginia. The band was dedicated to recreating the Glenn Miller sound, and the arrangements reflect Greco’s skill in adapting standard tunes to this style. Greco passed away in Weston, Florida, in 2003.

The collection is arranged in seven series, each focusing on different types of ensembles: Big Band, Nine-Man, Tenor, Four Horn, Ten to Twelve Man, Two-Way, and Three-Way. Instrumental parts are included for each piece, and if a vocal part is included, that is indicated in the finding aid.
