Procol Harum are best known for their Summer of Love classic single "A Whiter Shade of Pale," but the rest of their catalog is equally strong. Take their follow-up single to "Whiter Shade"—this song, "Homburg," which was released in late 1967. It's just as good as their first single, even if it mines the same veins: a slow, drowsy, hymnlike sound with surrealist lyrics from Keith Reid and a heavy reliance on the piano and organ interplay between Gary Brooker and Matthew Fisher. But this tune also offers the excellent drumming of B.J. Wilson (who didn't appear on the debut) and just as unforgettable a melody, even if it's not as celebrated.
Procol Harum were relatively celebrated in their time—and Shine on Brightly (1968), A Salty Dog (1969) and Home (1970) are among the greatest albums of an era that was riddled with great albums—but they appear to have been somewhat forgotten today, other than that one terrific song of theirs. Here's proof that there's lots more.
