Saxophone and piano free improv

For the beginning part, I was inspired by the Art Ensemble of Chicago, the Kabalaba live in Montreux, where I believe it's Lester Bowie, does baby sounds with just a horn mouthpiece! So I tried replicating this with a reed from a saxophone! I also discovered that I could do a very special harmonic sound with the bottom note specifically (while I'm writing this, I realise that the sax is in BB, and the note I'm playing is BB, so this all makes sense now!), so I played around this, while maintaining the pedal from the piano, so it creates a harmonic reverb... I will post the noise version of this right after!
