Going Off on One is the second live album released by the international progressive rock group The Tangent. It was released as a double CD/single DVD format (available separately), but also as a limited special edition, containing both CDs and the DVD, plus a deluxe digipack cover with enhanced artwork and extended booklet.
Songs that appear on the DVD were recorded live at Club Riga, England, in September 2006. Tracks 10-13 (disc two's first four tracks) were recorded on May 1, 2005 at RoSfest, at The Colonial Theater, Phoenixville, PA. "America" is the "missing piece" from the show recorded and released as Pyramids and Stars.
The DVD contains extras featuring a 1981 concert by Andy's band "A New Opera" (with Lindsay Frost, David Million, David Albone, and Simon Albone). There is also Tangent rehearsal footage show on a single video camera at Mushroom Studios in Rayleigh, Essex.
