PTX and Stromae

"PAPA" HAS GOT SOME BRAND NEW FANS: Belgian Euro-pop/EDM artist Stromae, who garnered global acclaim for his smash single, "Papaoutai," celebrates the conclusion of his first-ever sold-out American tour with RCA viral a capella sensations, Pentatonix. The latter earned 3m+ YouTube views on their cover of "Papaoutai" in just two weeks. The song can also be found on their just-released EP, PTX, Vol. III, which debuted in the Top 5 last week. Other celebs are falling head over heels for the rising star. Republic labelmate Lorde tweeted, "Stromae has one of the best shows I've ever seen. So smart, well-paced, lit, and constructed and the SONGS," while Sam Smith announced, "Everybody needs to know about Stromae!!" (10/8p)
