The record kicks off with the bouncy "Sad Angel," in which Buckingham and Nicks harmonize over looping guitar and Mick Fleetwood's driving beat. "Hello, hello sad angel, have you come to fight the war?" they ask.
The rest of the EP includes the classic-sounding "Without You," which started as a track for Buckingham Nicks, the duo's pre-Mac group. There's also a piano ballad by Buckingham called "It Takes Time" and the album closer "Miss Fantasy."
It's their first new music since 2003's "Say You Will," which debuted and peaked at No. 3 on the Billboard 200.
The band told Billboard in February that, "Big, long albums don't seem to be what everybody wants these days." Whether a full-length album emerges from this current reunion is entirely up to fans, Nicks said.
"[Let's] see if the world does want more music from us," Nicks said. "If we get that feeling, that they do want another 10 songs, we can reassess."
Fleetwood Mac is on tour until June. Watch our interview with the group below:
