Lady Antebellum and Earth, Wind & Fire Play 'September' at 2017 CMT Music Awards

The 2017 CMT Music Awards closed with a strange pairing that might not sound good on paper, but damn, did it sound good to the ears. Country trio Lady Antebellum joined forces with R&B legends Earth, Wind & Fire for a two-song collaboration to preview the upcoming special CMT Crossroads: Earth, Wind & Fire and Friends, which airs June 23.

First, Lady Antebellum performed "You Look Good" from their soon-to-drop album Heart Break, with EWF's signature horns backing them. But things really kicked into party mode when Earth, Wind & Fire busted out the irresistible "September," with Lady A handling some of the verses on the iconic 1978 disco/soul classic.
