The Miles Davis Nonet didn't last two years and released only four 78s during their lifetime, but these tracks not only mark a vital shift in jazz history, they're some of the most gorgeous arrangements ever put to tape. Just starting their careers, future icons Davis, Gil Evans, Lee Konitz, and Gerry Mulligan create a dynamic new sound rooted in rich harmonies and placid, almost meditative tempos. The deceptively casual "Boplicity" and celestial, shiveringly beautiful "Moon Dreams" still sound startlingly modern decades later.
