Only recordings of a high quality and a unique nature were considered for the core Tangerine Tree volumes.
These recordings were professionally re-mastered and released on CD-R and accompanied by high quality artwork for the CD labels and case liners.
The Tangerine Tree project was discontinued on 17 October 2006 by Heiko Heerssen due to legal concerns and personal reasons.
Ricochet is a composite "live" album, produced from hours of audio tape recorded during the French and British tours.
The only definitively identified source is "Ricochet, Part Two" from the 23 October 1975 concert at Croydon Fairfield Halls.
