The Mahavishnu Orchestra's personality clashes were as explosive as their performances, and consequently the first incarnation of the group split in late 1973 after two years and three albums, including a live recording entitled "Between Nothingness & Eternity". In 2001 the "Lost Trident Sessions" album was released; recorded in 1973 but shelved when the group disbanded. McLaughlin then reformed the group with Narada Michael Walden (drums), Jean-Luc Ponty (violin), Ralphe Armstrong (bass), and Gayle Moran (keyboards and vocals), and a string and horn section (McLaughlin referred to this as "the real Mahavishnu Orchestra"). This incarnation of the group recorded two more albums, "Apocalypse" with the London Symphony Orchestra and "Visions of the Emerald Beyond". A scaled-down quartet was formed with McLaughlin, Walden on drums, Armstrong on bass and Stu Goldberg on keyboards and synthesiser, which generated a third "Mahavishnu 2" recording in 1976 largely due to contractual obligations, "Inner Worlds".
