Chris Willman Senior Music Writer and Chief Music Critic “The Voice” has not been much concerned with current Broadway voices until now. That’ll change in a big way with this coming Monday’s episode, which will feature a show-stopping number from “Shucked” — marking the first time a song from a currently running Broadway show has been featured on the long-running singing competition series. The song is “Independently Owned,” a major nightly showcase for Tony nominee Alex Newell. It’s been cited as the rare example of an original Broadway musical having its first and possibly biggest standing-ovation number come in the middle of the first act… and it’s a testament to “Shucked” as a whole that the production doesn’t feel like it’s going downhill from that early barn-burner.
