Interesting harmony

Ok so it's a major triad in third inversion with a note a whole step below the root. I know the final note mentioned is a fifth below the key center, but other than that I don't know what to make of it. I know it's super useful when trying to create a sense of ambiguity and I use it all the time but I have no conscious knowledge of how it works (I don't even know how to define it as a chord). I feel like there are many opportunities generated by using this chord that I'm unaware of. Maybe that's why it sounds so mysterious to me. Anyways, if you could help me sus out the meaning and utility of this chord it would be much appreciated. Thanks.

Couple ways to interpret this:

E major with added 4th (11th in jazz), or an Esus with the third as well (less common)

A major 9 chord in second inversion with no third.

Just wondering, do you see the same significance of this chord that I do?

Reminds me vaguely of the close of one of my pieces.

@Quinn This kind of lydian feel created by 2 major chords a whole step appart over a pedal note is really nice. It's used by Joe Satriani in "Flying in a Blue Dream" almost exactly like that. Really recommend listening to that song, it's great.

Yes, nice one.
