One of the covers is a lo-fi version of "Baby, I'm Gonna Leave You." The song was first performed by Joan Baez during the early sixties and then popularized by Led Zeppelin on their debut album.
The second cover is the Roy Orbison hit "It's Over."
While these covers may seem a bit random to even Cyrus fans, the singer had a good reason for sharing them. According to a recent Twitter post, Cyrus intends to perform both of the covers as part of her current worldwide concert tour.

Cyrus is nearing the end of her Bangerz Tour, which began in February. The tour is named after her most recent album and has made stops in countries throughout North America, Europe, and South America.
Cyrus made a shocking and career-shifting appearance last year at the 2013 MTV Video Music Awards. Her twerking performance with Robin Thicke signaled a wild departure from the pop star's formerly wholesome persona.
The tour and new persona could be taking a toll on the singer, though. Text chat images posted on Cyrus' Instagram account this week show that she recently reached out to her father Billy Ray Cyrus for advice when she was feeling "down."
