Reception
Miles Davis at Newport 1955–1975: The Bootleg Series Vol. 4 received positive reviews on release. At Metacritic, which assigns a normalised rating out of 100 to reviews from mainstream critics, the album has received a score of 92, based on 14 reviews which is categorised as universal acclaim. Matt Collar's review on AllMusic stated "Miles Davis at Newport details the association between Davis and the festival, each performance serendipitously documenting his ever-morphing sound, from swinging cool jazz in the '50s to aggressive, free jazz-influenced modal bop in the '60s and finally to funky, acid-soaked fusion in the '70s." PopMatters's John Paul gave the album 10 out of 10 saying "Perhaps no other recording better illustrates how Miles Davis bridged the gap between jazz's old guard and its younger visionaries." The Observer's Dave Gelly said "Summer is traditionally the season for unearthing treasures from the jazz archives, and this is a real prize."
