I know that these things can be a shameless cash-in, but still there are some particular bands or albums that seem to have been overlooked.
Off the top of my head I was thinking of re-issues I would buy (if the bonus content was right)-
Faith No More - The Real Thing and Angel Dust
Idlewild - The Remote Part (if only to compile all the amazing b'sides in one package)
The Verve - A Storm In Heaven, A Northern Soul and Urban Hymns (would all need to have bonus live stuff)
Husker Du - the complete back catalogue (highly unlikely to happen but we can but hope)
Primal Scream - Vanishing Point and XTRMNTR
Hope Of The States - The Lost Riots (again for the b'sides)
What else is conspicuous by its absence??
