Between Nothingness & Eternity is the first live album of Mahavishnu Orchestra, and last with the original line-up, released in 1973. According to the Mahavishnu Orchestra Gigs listing by Walter Kolosky, it was recorded live at the Schaefer Music Festival, held in Central Park, New York on August 17 and 18, 1973, even though available recordings seem to prove that all of the material from the album was actually taken from the second night only. Originally, Mahavishnu Orchestra's third album was to be a studio one, recorded in June 1973 at Trident Studios in London, but was scrapped during the final days of the project. A live album containing versions of three out of the original six tracks came out instead. The original studio album was later released in 1999 as The Lost Trident Sessions.
