The Mix Tape, Vol. IV is the fourth installment in Funkmaster Flex's Mix Tape series (fifth release overall), released on December 5, 2000 through Loud Records. This installment was a departure from Flex's previous Mix Tape releases, which consisted of freestyles mixed with previously released songs. This, however, was mostly made up of original songs with original production with Funkmaster Flex providing the DJ mix. The Mix Tape, Vol. IV was a success, peaking at 26 on the Billboard 200 and becoming Funkmaster Flex's fourth consecutive album to earn a gold certification from the RIAA. To date this remains the final entry in the Mix Tape series, a fifth installment was planned for release on January 15, 2002, however Loud Records was shut down and the album's release was cancelled.
