Backed by a sizable ensemble that includes live strings and horns, Diana Ross is on tour playing hits from a career that has spanned some serious stylistic turf: soulful girl-group pop with the Supremes, bluesy vocal jazz in Lady Sings the Blues, and the hands-in-the-air disco of "I'm Coming Out." The show is called More Today Than Yesterday, after the Spiral Starecase hit she covered on 2006's so-so I Love You. But according to reports from the road, the set list (which evidently includes a tribute to Michael Jackson) has more to do with yesterday than today. Given Ross's still-powerful voice and wonderfully diva-tastic hair — plus her rep's promise of "breathtaking costumes and stage designs" — that shouldn't be a problem. "Breathtaking," people!
