"He extends himself only to express himself. Alone among rock's great figures — and even in that company he is one of the greatest — Morrison is adamantly inward. And unique. Although he freely crosses musical boundaries —R. and B., Celtic melodies, jazz, rave-up rock, hymns, down-and-dirty blues — he can unfailingly be found in the same strange place: on his own wavelength."
January 1, 1970
