 The first Led Zeppelin box set, featuring tracks remastered under Page's supervision, was released in 1990 and bolstered the band's reputation, leading to abortive discussions among members about a reunion. This set included four previously unreleased tracks, including a version of Robert Johnson's "Travelling Riverside Blues". The song peaked at number seven on the Billboard Album Rock Tracks chart. 1992 saw the release of the "Immigrant Song" / "Hey, Hey, What Can I Do" (the original B-side) as a CD single in the US. Led Zeppelin Boxed Set 2 was released in 1993; the two box sets together containing all known studio recordings, as well as some rare live tracks.
