Pianist Luisa Imorde loves innovative combinations: following on from circus dances by Schumann and Widmann and the affair of honour between Woelfl and Beethoven, she now prepares to cast light on Johann Sebastian Bach and Nikolai Kapustin.

This is an album whose spectrum ranges from Baroque counterpoint through to polyrhythmic jazz sounds.

They could hardly be further apart: Bach and Kapustin lived 250 years apart and on two different continents. One is the indisputable supremo of European classical music, the other a Russian composer known only to a few aficionados in central Europe, someone who transforms musical jazz sequences into formal, classical structures. On Moon Rainbow they alternate.

“There is no established listening convention for this. The result is a foundation of literally unheard sounds, which makes it possible to hear anew – so to speak – a familiar old piece by Bach in this new context,” explains Imorde. Nikolai Kapustin is hardly a household name, even in Europe. Born in 1937 in Horlivka in what was then the Ukrainian Soviet Socialist Republic, the composer and pianist began pouring improvisatory ideas into forms that were well known in the Baroque era.

What he wrote sounded like virtuoso jazz, yet every single note, every accent and all the dynamics are clearly defined. Preludes, Fugues, Inventions – even at this level, everything ultimately leads to Bach.

She is the first one to record the piece Moon Rainbow, which lends its name to the album: “In comparison to the other compositions by Kapustin, Moon Rainbow is very varied. The piece develops a very rich fabric of tonal colours. That too is why the title is so perfect for the work.” It did not take long for her to decide that the album itself should take that title; she figures that just as Kapustin is barely known, most people have no idea of the existence of moon rainbows, yet both are worth discovering. She wishes to encourage listeners to read between the lines: “When a piece by Bach dies away and a work by Kapustin begins, there is a magical moment, because just in that short space of time it’s not clear where the music will go next.”
