William Shatner's 1968 album The Transformed Man has been a cult classic for four and a half decades. It's tempting to think of the record as "so bad it's good", which has always been a pretty shabby way to enjoy oneself. We wouldn't go as far as good, but it is compelling. Shatner does his strange, overblown exclamations and Captain Kirk pauses over classics like Lucy In The Sky With Diamonds.
His 2004 album Has Been, with Ben Folds, un-jumps the shark as a genuinely witty and moving reappraisal of an aging actor's career, while 2011's Seeking Major Tom saw him collaborate with the likes of Ritchie Blackmore, Johnny Winter and Bootsy Collins. Seriously.
