Last night, Stefani Joanne Angelina Germanotta aka Lady Gaga rocked it out at Nashville's East Nashville music venue--the first stop on her Bud Light-sponsored Dive Bar Tour to promote her forthcoming album Joanne. The singer debuted three new songs, "Million Reasons," A-Yo," "Sinner's Prayer," all of which straight-up, stripped-down country rock/pop affairs.

Wearing the same, pink felt hat on her stunning album cover, and a sequined cowgirl leotard, Gaga kept it simple, walking directly through the crowd to begin her sort but incredible set.

A-Yo has producer Mark Ronson all over it...

Slay us, Gaga.

Watch the full set below...

...and listen to the official audio for her heart-wrenching ballad "Million Reasons."
