- Mac Miller in 2011
An alternative version of "Dunno" from his August release, Swimming, features Miller's raspy vocals accompanied by a piano.
"Nothing from Nothing" is a cover of Billy Preston's 1974 hit of the same name, which again features Miller singing alongside a piano.
Stripped of instrumentals and backup vocals, the two tracks are both touching and haunting. Considering Miller's prolific output, this may be the first of a slew of unreleased music, or so Miller fans can hope.
