OVER-INDEXING: TRAVIS, RAYE, STAPLETON DUE
ON SNL

Saturday Night Live has unveiled a distinguished trio of upcoming musical guests via its distinctive index cards.

Cactus Jack/Epic's Travis Scott will bring his trademark frenzy to the NYC institution on 3/30; he'll be introduced by host Ramy Youssef.

Human Re Sources breakout RAYE, who recently earned more BRIT Awards than anyone ever, will deliver the "Escapism." on the 4/6 installment, which is due to be hosted by SNL alumna Kristen Wiig.

On the 4/13 telecast, Mercury Nashville's husky-voiced trophy magnet Chris Stapleton will shake the rafters, no doubt supplementing the Ken-ergy of host Ryan Gosling.
