He said at the time that the trio was “searching for a free sense of tonality and form”.

[2] The album title comes from Giuffre's sense that a meeting (fusion) of minds of the musicians was required in the free improvisation sections of the performances.

The contemporaneous DownBeat reviewer commented that the recording was dominated by Bley, not Giuffre, and concluded that it was "off the beaten track in exploring possibilities for this type of guided democracy in jazz".

The elegance and grace of this album didn't set the American jazz world on fire as Free Fall would the next year, but it did set up further textural and architectural possibilities for the trio's next album, Thesis".
