had previously suggested that Hejira was the last album that the general
public bought; a new theory is that DJRD sold poorly because it was a
double album. Lots of double albums did/do poorly (the White album,
T'log); I believe there is too much new material to digest properly - It's
not the right "chunk" of new material.
DJRD sold over 500,000 copies ("gold"), I recall reading, in its first year
of release. While not a big hit, that's still rather significant, especially
back in the 70's when multi-million (multi-platinum) albums were somewhat
rare.
