Wolfgang's Vault has added four Miles Davis concerts from the early 1970s to its collection of free audio streams. The concerts includes two of the trumpeter's shows from 1970 at the Fillmore East, a 1970 performance at Tanglewood, and a 1971 concert at the Fillmore West.
Wolfgang's Vault began as an online archive of material from concert promoter Bill Graham, and has grown to encompass ten different archives, ranging from Crawdaddy magazine to the King Biscuit Flower Hour radio program. It offers "free music streaming online...hundreds of available concert recordings from the last 40 years, digital downloads and thousands of rock items including posters, photos and t-shirts available for purchase."
