I recently discovered an interesting music website, Wolfgang’s Vault. “The World’s Greatest Collection of Vintage Concert Recordings” has just acquired recordings from the  Newport Jazz and Folk Festival.
Wolfgang’s Vault now offers concert recordings by artists like Ahmad Jamal Trio, Dizzy Gillespie, The Four Freshman, Gene Krupa Quartet, George Shearing, Herbie Mann Sextet, Horace Silver Quintet, Jimmy Smith Trio, The Mastersounds, Oscar Peterson Trio, Maynard Ferguson, Stan Kenton Orchestra, Thelonious Monk and others as a MP3 download, or free music stream.
