1960年3月から1970年5月までのボツになった演奏12曲を寄せ集めてしまったアルバム。「しまった」というのは、マイルスの沈黙期にリリースされたからということ。60年代から70年代へかけてのマイルスを俯瞰することはできるが、あくまでも「ボツ集」であることは間違いない。マイルスを追いかけて追いかけて、それでも新たな発見を見出したいために聴くアルバム。その結果は、人によって時代によって違うのだろう。Directions（方向性）は、マイルスが決めたのではなく、聴き手が決めるのだ。この過去形と現在形が大事。
12曲は60年3月11日から録音順に並んでいるが、なぜか最後の2曲はKonda（70年5月21日）の次にWillie Nelson（70年2月27日）が配置されている。2枚組LPのD面の2曲なので、逆順にした理由が分からない。ライナーノーツ（LP：岡崎正通氏、CD：村井康司氏）には、このことは書かれていない。
