This box set contains 82 tracks recorded by Miles Davis between 1945 and 1950. Miles' spark of genius was already apparent right from the start, and it's clear after listening to this set why Prestige gave him a lucrative recording contract which he would fulfill from 1951-1956 on his way to super-stardom. His distinctive sound on the trumpet is unmistakable here, even as a twenty year old…a sound that would delight the world for decades! This set is solid gold, filled with nuggets of beautiful jazz from start to finish. Many people may be content to limit their early Miles Davis collection to the Complete Birth Of The Cool CD, and that's fine, but you'll be missing out on lots of great music from one of the finest jazz artists of the 20th century!! The sound quality on this box set is great, save for a handful of recordings that are a little garbled but were included anyway because the playing is so beautiful.
