Interesting. Just as with other types of music I "discover", I am finding there are different types of Jazz. So far, "slow jazz" and "sleepy jazz" seem to yield the most results. "Late night" jazz also has promise. I have been going through youtube jazz channels, where people have compiled a bunch of it on one page. There are many of them. I just listen to a few seconds of each and move on till I find something close.
The problem is that jazz seems to be sorted by what instruments are used. This music we are trying to ID has a whole bunch of instruments in it (that's why I call it "Succotash"). I think there's about 20 instruments used in it, most of which I can recognise, but some are something I don't recognise. There are also a few electronic instruments, along with some electronic effects.
BTW, is that bass beat an electric base guitar, or is it a bass fiddle?
