Punk rock's poet laureate Patti Smith ranks among the most ambitious, unconventional, and challenging rock & rollers of all time. When she emerged in the '70s, Smith's music was hailed as the most exciting fusion of rock and poetry since Bob Dylan's heyday. With her androgynous, visual presentation echoing her unabashedly intellectual and uncompromising songwriting, Smith followed her muse wherever it took her, from structured rock songs to free-form experimentalism. Her most avant-garde outings, such as 1975's Horses and the following year's Radio Ethiopia, borrowed improvisation and interplay from free jazz, but remained firmly rooted in primal three-chord rock & roll.
