Much like her critically acclaimed Sound of Music medley, Lady Gaga has once again proved what a powerhouse vocalist she is after covering John Lennon's "Imagine" and it was all too gorgeous. 

On Friday (June 12), Mother Monster took a break from her worldwide trek with Tony Bennett to appear at the 2015 European Games Opening Ceremony, which were held in Baku, Azerbaijan. In a professional recorded video, which was posted on the singer's YouTube account, Gaga walks towards a floral decorated piano in a pitch black stadium, before belting out the iconic song.

Gaga shared a behind-the-scenes snap of her rehearsing for the number on Instagram, and we would like to think that she would have made Lennon very proud.
