In the early 90s, Jérôme Soligny met Mike Garson, the extraordinary pianist who transformed David Bowie"s music on Aladdin Sane. Soligny invited him to make an album of piano covers of Bowie"s songs, and in 2011 he released The Bowie Variations For Piano. In 2024, to accompany his book Rainbow+, Soligny launched The Rainbow Variations. The album features 9 Bowie covers, including "Space Oddity" and "Wild Is The Wind", and one original. Mike Garson displays the full extent of his talent one last time on this project, which brings their collaboration to a close.
