I love this clip of Freddie Mercury and Brian May in the studio working on the song One Vision.
In the first few seconds, Freddie says, “You can do better.”
The pair then spend the next few minutes trying new sounds and approaches.
What I love about it is the respect and trust between the two musicians, as well as the lack of ego. Hard feedback doesn’t have to taste like vinegar when both people know the criticism is levied at the work, not at the person.
