Pops: A Life of Louis Armstrong, by Terry Teachout (Houghton Mifflin Harcourt, 2009): 475pp. Hardcover, $30; paperback, $16.95.
If you plan to read just one book about Louis Armstrong, whose virtuosic cornet solos pushed jazz past rudimentary ensemble playing and launched his phenomenal career as an instrumentalist and singer, make it Pops. Teachout built it on brickwork laid by authors who preceded him, so you'll benefit from their research, as well as from narrative on 650 previously private reels of tape that Armstrong recorded and archived. Moreover, Teachout is a musician and music critic who offers opinions on his subject's discography.
Few people seem to realize that Armstrong (19011971) called himself LOU-iss. "All White Folks call me Louie," he once noted, and in some instances that may have been patronizing. In others, it was surely an instinctive response to the man's infectious warmth and informality.
