I purchased Miles Davis’ Decoy as a new release in 1984. In my world- then as now- all genres are on equal footing. Decoy had to compete for my attention with Prince’s Purple Rain, Run-D.M.C.’s self-titled debut and Talking Heads’ Stop Making Sense. Decoy held its own. My bond with Davis’ unfairly maligned 1980s work is indelible. Consequently, the new 211-minute set That’s What Happened 1982-1985: The Bootleg Series, Vol. 7 resembles musical manna from heaven. The essential outtakes and live recordings aren’t merely further affirmation of the icon’s genius. Davis’ forty-year-old discards are more vital than a disheartening share of the jazz being made today.
