"Roy Orbison left Monument for MGM Records in 1965, not long after "Oh, Pretty Woman" gave him his second number one single in 1964. He did not see those heights again during his stint at MGM, but it wasn't for lack of trying. During those eight years, he released 12 full-length albums - another, One of the Lonely Ones, was rejected in 1969 and wasn't unearthed until 2015 - and a clutch of non-LP singles, all rounded up and released in this 13-disc box set, The MGM Years 1965-1973 (One of the Lonely Ones is not part of the box) ... there are a handful of albums that do work (Hank Williams the Roy Orbison Way, The Big O, Roy Orbison Sings Don Gibson, Cry Softly, Lonely One), but taken as a whole, this box feels like a series of compounding detours".
