Led Zeppelin – Physical Graffiti (1975)
Led Zeppelin I, II, III, IV? Depends on the preamble.
Which records are solid? All of the above!
Which is their best? None of the above.
The (temporarily) correct answer: Physical Graffiti.
The cover may be lacking a roman numeral but there is no shortage of excellence on this double LP. Not even a Diddy sample can taint Kashmir!
