Calling this material "throwaway stuff" doesn't seem to make much sense when it applies to the collaboration of these two. Some of Byrd's solo material, BN or not, may not be the stuff of legends but there is some fine material there: Transition, Savoy are very good and let's not forget his appearances on some of the Wallington cds. As far as Blue goes, much of his BN material is memorable as is his Riverside work. I often reach for the Mosaic. It's one of my favorites.
