In an effort to free up space for Hendrix's lead vocals, further reduction mixing was completed for "Are You Experienced?" during a session at Olympic on April 4, 1967. With the title track complete, the Experience shifted their focus to the January 11 rough demo of "Third Stone from the Sun". Chandler decided that they should discard the original De Lane Lea tape and record a new version of the song. During the session, Kramer prepared a reduction mix of "Highway Chile", which made two tracks available for Hendrix's lead guitar and vocal overdubs. Though stereo and mono mixes were completed for the song, Chandler preferred the mono version, which he paired with "The Wind Cries Mary" for release as the group's third UK single. A reduction mix was prepared for "Love or Confusion", and Hendrix took advantage of the newly vacant tracks by adding lead guitar and vocals. A final mix was completed before the end of the session. On April 5, Chandler participated in a mastering session at Rye Muse Studios for "Highway Chile" and "The Wind Cries Mary", during which preparations were made so that Track could begin manufacturing records. On the 10th, he and the Experience returned to Olympic, spending the bulk of the session on editing dialogue segments for "Third Stone from the Sun", which were then slowed down and mixed into the song. Kramer concentrated his efforts on the song's complicated mix: "The song was like a watercolor painting ... each track was composed of four, fairly dense composite images."
