by Richard S. GinellThe 1992 CD reissue of the Keith Jarrett "American" Quartet's last recording session combines most of the contents of the LPs Byablue and Bop-Be, omitting "Yahllah" and "Konya" from the former and "Pyramids Moving" from the latter. (Tellingly, in keeping with conservative '90s tastes -- never mind the time-limit excuse -- the deleted tracks are the ones which have an experimental Middle Eastern flavor.) Still, this partial sampling of the session indicates that the quartet went out on a high note, still exciting and inventive, the old interplay very much in action, unrepentantly acoustic in an electric era. Like the LP of the same name, "Byablue" brackets the CD with a group version at the beginning and a solo piano benediction at the close, which under these conditions becomes an emotional elegy for the soon-to-be defunct quartet by its leader.
