That is a shame. Time to start listening! Thanks fezz parka for FINALLY getting to the real issue. Jazz existed BEFORE bebop, Miles, etc. It was even popular then! But there would have been NO Miles Davis without Louis Armstrong. His success as a popular entertainer, and his loveable image as the guy with the gruff voice that sang pretty tunes, has overshadowed his importance as THE FIRST GREAT JAZZ IMPROVISER. On trumpet (cornet) and vocals. No Louis - no Miles, no Monk, no Bird, no Wes, none of them. I love "modern" jazz and all the recordings mentioned have a lot of merit, but I am appalled that so many of you completely ignore the first part of jazz's musical history as do so many jazz fans these days. So you want to learn about jazz from the root source? Check this out: The Hot Five and Hot Seven recordings: https://en.wikipedia.org/wiki/Louis_Armstrong_Hot_Five_and_Hot_Seven_Sessions "The Louis Armstrong Hot Five and Hot Seven Sessions were recorded between 1925 and 1928 by Louis Armstrong with his Hot Five and Hot Seven groups. According to the National Recording Registry, "Louis Armstrong was jazz's first great soloist and is among American music's most important and influential figures. These sessions, his solos in particular, set a standard musicians still strive to equal in their beauty and innovation.""
