Beyond those, Carlile's canny ability to convey universally-relatable sentiments through songs, often based on her own experiences, solidified her standing as one of the most beloved stars in Americana and beyond.

Unlike Elton, Carlile came to Joni much later in life, something she's been candid about. Well before acknowledging that Mitchell was in the house and going to perform, Carlile played a song she said was the first of hers to be inspired by Joni.

In her initial Instagram post, Carlile wrote, “It finally happened… and although Belinda Carlisle and I are now best friends. We ARE NOT the same person!” The Go-Go's also tweeted an image of Carlisle with the whole band, saying, “Look who we met tonight! Brandi Carlile rules.”
