Recording of a train journey somewere between katowice and wroclaw, poland. It's a binaural recording done in the middle of a train, standing next to a window.
Underground subway platform recording. A man is ranting and making guttural noises for the first half. Someone audibly tells him "go home", and the man lets out a final gawp. As he leaves, a street performer with saxophone mockingly plays some bach. Recorded with an edirol r-09.
