Tumblers from the Vault (2016), is a compilation of the work of experimental/electronic jazz band Syrinx. The songs were recorded in the early 1970s during a two year period, and one can definitely hear similarities with some of Pink Floyd's work from that era, especially in their use of synthesizers to create atmosphere.
The self-titled opening track will give you an idea of their originality, their blend of styles and genres and brilliant arrangements which mix real instruments with synths in such a way to form a beautiful cacophony; one that could be seen to have influenced the sound of contemporary bands such as Animal Collective.
