The Stockholm and Berlin recordings were made during Ayler's thirty-day 1966 European tour, which lasted from November 3 through December 2. The tour, which also included Lörrach, Rotterdam, Paris, and Copenhagen, came about when
Joachim-Ernst Berendt, director of the
Berlin Jazz Festival, asked promoter
George Wein to include Ayler's group in his annual festival tour. (
John Coltrane had also been invited to participate, but declined due to health issues.)
Henry Grimes and
Sunny Murray were unable to accompany the band on the tour, so Ayler asked bassist William Folwell and drummer
Beaver Harris to join him. The group also included Ayler's brother
Donald on trumpet and violinist Michel Sampson. According to Ayler biographer Jeff Schwartz, the recordings show Ayler using a modular approach to his music, with thematic sections that can be reshuffled interspersed with improvisations, including brief solos by Harris and Folwell. Schwartz noted that Ayler's vocalizations on
Pharoah Sanders' "Japan" on the European recordings are the first time he is heard as a singer. He also suggested that the singing may be an extension of the moaning sounds that Sunny Murray emitted while playing the drums. ==Reception==
