I didn't think I'd do an MJ post. But as someone who has loved music & dance my whole life long, it's hard not to: Michael had cataclysmic impact on how everyone understood the essential fusion of music + dance, and how we'd newly see the whole made from the two halves.
We tend to revere artists more when they are gone too soon. "Elder statesman" fits with grace only a few of the genius musicians: Stevie, Quincy Jones, Bonnie Raitt, Elton John, Aretha. Dancers seem to have even less leeway as we tilt toward the grave - Baryshnikov, Madonna, and Kylie excepted, the viability of dance as a lifelong profession is fleeting, at best.
