In a preview of "Late Registration" on April 20, 2005, West appeared on New York radio station Hot 97 and played the lead single "Diamonds from Sierra Leone". The album was originally set to be released on July 12, 2005, but was shifted to August 16 by Roc-A-Fella/Def Jam. It was pushed back once more to August 30 by West himself as he needed more time to complete the album. "Late Registration" was anticipated to become the biggest-selling record of the year and over 1.6 million copies were distributed to stores in preparation of its first week of release. On the iTunes Store, the album became one of the most pre-ordered titles in the online digital media store's history. West filmed a live album featuring tracks from "Late Registration" and "The College Dropout", titled "Late Orchestration" which was released April 2006.
