Name that chord...Please and thank you!

I meant that it's pretty clear from the recording (and has already been discussed) that bass stays on B for both chords. Why should we talk about E, or any other note for that matter?

Because if we're really talking about what to do with these two chords, it's ambiguous just given that recording. That recording is yet to be a whole anything, it's just an idea.

For me (being interested in the thing) the fun part is that there are the two angles to this in practice ANYWAY.
(why should we talk about E when one of the chords is E major? HMMMMMM...)

It can be quite rich what I'm indicating. In true modal usage, while there is one 'Sa', 'I', the real tonic, when you have another plateau, there are other aspects to the 'mode' which are revealed by another angle. HERE, it is ambiguous because no one is supplying an anchor. It's a sketch. You're certain about 'the bass'? WHAT BASS? I don't know, and this, right here, is my thing.

This is my area of interest. So just maybe I'm saying something. Apparently it isn't anything interesting to you.*
I don't think you get what I'm talking about, have contributed little yourself to this discussion *but this you took the time to do?

Well, if you look at the two chords from an E POV, yes, you could as well treat it as E mixolydian.
But IMO, in this case the bassnote really gives it away.
If there was an E being played, things might be different (I have stumbled upon a few songs in my life where I seem to hear the tonic different than most others, could come up with an example...).
But, if we started to go that route, we could as well just say Bmin - E is an unresolved II-V movement and center whatever melodies around A. And that'd certainly resolve in a debate when or when not which chord becomes tonical. Perhaps not exactly what is needed for this little chord vamp.

Don't get too excited. I get what you're talking about, it's not rocket science.
I don't know if you've read the whole thread but in my first post I tried to answer the OP's question. It was a simple question that needed a simple answer. I agreed that Sascha analyzed it even better and I think the matter was really done there. It's all too clear it's a B Dorian vamp.
If you want you can go on rumbling about how it *could* be a substitute II-V in Eb but I don't think it helps anyone.
