Masterful Mystery Tour is the second album from Beatallica. It contains 12 tracks, which are mashups (or Bashups) of songs by the Beatles and Metallica. As with their first album Sgt. Hetfield's Motorbreath Pub Band, this album contains re-recordings of songs from the band's EP releases A Garage Dayz Nite and Beatallica, plus six new Beatles/Metallica mashup songs. The album cover is a parody of The Beatles' Magical Mystery Tour and Metallica's Master of Puppets. Beatallica released a video for the single "Hero of the Day Tripper" on YouTube, the band's first official full-length video.
