It’s not often you see an educational publishing company fill a venue as mammoth as Mohegan Sun Arena, but McGraw-Hill are doing that this week.

Wait, what? The McGraw-Hill show here is NOT about the publishers?

Well, of course not. This concert extravaganza stars the country music dynamic duo of Tim McGraw and Faith Hill. The couple famously met and fell in love on tour, which was appropriately named Spontaneous Combustion. That was 21 years ago. Since then, Hill and McGraw have teamed up for the first Soul2Soul tour in 2000 and the Soul2SoulII tour in 2006. They paired up for a Vegas residency in 2012-13, too.

Now comes the Soul2Soul World Tour, which lands at Mohegan Sun Arena for concerts on Friday and Saturday. 

Hill and McGraw are each stadium acts on their own, so the combined star power is bound to be incredible. And they are scheduled to release a joint album later this year — the first one they've done — so anticipate plenty of duets during the shows.

Tim McGraw and Faith Hill, 7:30 p.m. Fri. and Sat., Mohegan Sun Arena; with The Shadowboxers; $79-$139; 1-800-745-3000.
