At sixteen he dreamed he was playing three instruments at once, and the next day went to a music shop and tried out all the reed instruments. He was taken to the basement to be shown "the scraps", and found two archaic saxophones which had been used in turn-of-the-century Spanish military bands, the stritch and the manzello; the first is a kind of straight alto sax, and the second looks a little like an alto, but sounds more like a soprano. Kirk took these and worked out a way of playing them simultaneously with the tenor sax, producing three-part harmonyby trick fingering. As there were often slight tuning discrepancies between the three instruments, the resulting sound could be harsh, almost with the characteristic of certain ethnic instruments, and this gave Kirk's music an added robustness.
