Good rhythm,timings not too bad, some notes sound a bit squeaky weak? sounds just as if you have too much mouthpiece in your mouth which is stopping you from getting a deeper sounding low note, i would take in just a bit less. Simple exercise passed on to me, is when you take the sax out before you do anything else, get the tuner out, and play a low Bb loudly and for a complete breath, so its a loud rich smooth steady tone, do this about 10 times, but do it every day. Then just play a Bb scale going up from Bb in the same strength.
By the end of a few weeks you will have strong Low Bb. Some people do this exercise everyday as they reckon it puts the whole sax in tune, if you tune up higher up the sax, then you have the problems of tuning lower down and problems with tuning further up in the higher register.

Overall sounded great

Nice! How long you play saxophone Jazz Cat?

That reminded me ” Rumble ” by Link Wray would be very cool. Its a few notes, plenty of room for sccops, growls. If I had a horn, and I’d give it a go . Guess, I’d need a backing track. Food for thought… Johnny ?? !!
