what cds should i pick up?
There are a number of Orbison compilations. Beware that many are re-recorded hits. The re-recordings that I have heard are actually quite good, but they are not, of course, the original hits. 'For the Lonely' (Rhino 71493) contains the original hits. There is a new 'Essential Roy Orbison' but it appears that here again, some of the original versions of songs (like "Running Scared" and "In Dreams") are missing. I am sure it is quite good though.
A 'Black and White Night' (now re-mastered) is an excellent later period video of a star-studded live date (with Springsteen as musical director, Tom Waits, T-Bone Burnett, James Burton, Elvis Costello, Jackson Browne, Bonnie Raitt etc.)
