Erm, not by a million miles was it the first, troub!

Even ignoring hundreds of classical and opera box sets, I have a number of box sets which were issued many years before Biograph: The Complete Buddy Holly issued in 1979 and the Chess blues box set Genesis issued in 1972 come immediately to mind... but Biograph is, as others rightly say, a great collection, imaginatively sequenced and brilliantly annotated. Bravo, Columbia or Sony or whoever you were in '85!

box sets I think, and may well have helped establish a market for them.
