While living in Boston, I took my then-boyfriend Kelley to see Standing in the Shadows of Motown. He didn't know most of the musicians involved (he said, when Joan Osborne appeared: "Is she one of The Osbornes?"), but he did know Chaka, and when she appeared at the end, he remarked, "She's blossomed!"
Anyone know what that whirling-into-the-stratosphere synth sound is called? Seems to have originated either here or on Kool & the Gang's "Summer Madness," and it's still being used in hip-hop samples today.
