As a big fan of Donald Fagen's music, these transcriptions are very accurate. The chord voicings for guitar are excellent and accurately reflect the complex harmonies in the tunes. A real treasure and great workout for musicians (especially guitarists) who are Fagen fans and don't have the requisite level of jazz harmony transcription skills. He's a great songwriter and it's a "wholesome harmonic mindbath" to have all the rich harmony at your fingertips and in your ears. It's all laid out and you play it and rejoice cause it doesn't just sound close, it's on the money! Green Flower Street Cmaj7-F#7-F6-E7 or Goodbye Look Fmaj7-B7#5-Bbmaj13-A7#5-Dm9-G11. His chromatic movement is cool.Out of print, way too bad. Now will someone lay out Zawinul/Shorter Weather Report harmonies accurately for guitar? I'm just growing old.
