Bach, performed on a modern copy of a period instrument: nothing new there. Until you discover the instrument in question is a recreation of the 1973 Moog System 55 modular synthesiser, lovingly handcrafted using, according to Moog’s website, all of the original documentation and circuit board and art files.

In 1968 Moog exponent Wendy (then Walter) Carlos unleashed ‘Switched-On Bach’ on an unsuspecting public (4/69). In doing so, she altered the course of musical history – pop and classical – forever. ‘Bach to Moog’ is part celebration of Carlos’s (in the eyes of some, dubious) achievement, part commemoration to mark 50 years since Robert Moog first introduced his large-format analogue modular synthesisers and 10 years since his death. But – and unexpectedly for this initially sceptical reviewer – it’s primarily an utterly exhilarating listening experience which will captivate old fans and newbies alike.

There’s a lot happening here which could quickly turn nasty: multiple synthesisers, multitracking, processed strings, synthesised brass and timpani, and some risky duetting between violinist Jennifer Pike and ‘Bach to Moog’ mastermind Craig Leon, record producer and arranger to the stars as well as an extraordinary composer and keyboardist in his own right. However, it never does, and what’s most striking is the exceptional warmth, depth and richness Leon produces from his analogue synthesisers, as well as his exuberant playing and imaginative arrangements. Ably supported by Sinfonietta Cracovia and with Pike so obviously getting the project, Leon manages to leave you with the sense you’re hearing this music for the first time and having an absolute ball into the bargain.
