Obsessive music fans know that every artist or band has a “canon” made up of albums recognized by fans,
critics and record labels as official releases.
Once an artist becomes established, however, opportunists commonly flood the market with rough takes on familiar tunes, rejected songs from
album sessions, cover versions played once for a lark, and bootleg live tracks of questionable sound quality. While
these new offerings usually contain a few rare gems and often provide insight
into an artist’s work process, they generally do not compare favorably to music released exactly as the performer intended.
The Book of Jubilees might well be called “Outtakes from Genesis”. At least, that’s what it reads like.
