Don't know how 'Strictly Personal' by Captain Beefheart has evaded me all these years but I finally bought a copy yesterday.
Just goes to show that, even focusing almost exclusively on the 50s/60s, relatively high profile artists and/or LPs can still be missed.
Next on my 'plugging the holes exercise' are 'Delay 1968' and 'Monster Movie' by Can and, on CD anyway, George's 'Wonderwall Music'.
Should be a giggle, I bet my wife can't wait!
