A rare recording of an historic event! The production team of Aeco and Katalyst have once again gone through the vast archives of the Art Ensemble of Chicago to come up with another gem. Featuring the classic line up of possibly one of the most innovative groups in the history of jazz (Lester Bowie - trumpet, Roscoe Mitchell - saxophone, Joseph Jarman - saxophone, Malachi Favors Moghostut - bass, Famoudou Don Moye - drums & percussion), this concert recording at the Frankfurt Jazz Festival in 1991 also features world renowned pianist Don Pullen in one of his rare appearances with the whole group. His concepts explore numerous subtleties and nuances within the improvisational potential of their original compositions and intensify the ever present energy of the group.
