The actual inspiration for Martinů's The Cat's Procession in the Solstice Night (Průvod koček v noci slunovratu, H 122) is not known, but based upon midsummer traditions of folklore, one could conjure an image of witches (transformed into cats) on their way to a convocation of magical powers. Written in 1919, it precedes Martinů's move to Paris and his "jazz period", and is the earliest of Martinů's piano works to show influences of jazz.
The recording of the song was first released by Naxos in 2007 (Giorgio Koukl).
