"Hot Rats" fyller 50! Dette er en limitert 6CD-boks med en hel haug med snacks, bl.a. 59 tidligere uutgitte spor. Her er hva Zappa Records sier om den:

"The Hot Rats Sessions box set celebrates the 50th anniversary of one of the greatest albums in the history of recorded music. The original 1969 Frank Zappa album was the first record to be recorded on a prototype 16-Track Tape Machine. Self-described as a “Movie For Your Ears,” it was technically the second solo outing for the composer and the album that put FZ on the map as a guitar player. The recording sessions produced a wealth of material that ended up being sprinkled among multiple releases during FZ’s lifetime. This mammoth six disc collection documents and compiles every composition recorded during those days in July 1969, along with an abundance of rare mixes, Vault nuggets and complete basic tracks mixed from the original multi-track masters by Craig Parker Adams in 2019.  Additional gems include images by original Hot Rats cover photographer, Andee Nathanson, and session photos taken by Bill Gubbins, liner notes by Matt Groening and essays by Ian Underwood, Andee Nathanson and Vaultmeister Joe Travers. 

The box set also includes a Zappa Land board game in celebration of this release with custom game pieces, dice and playing cards."
