OK. Love the guitfiddling...solid.
The bass pan L, I have no problem with: blues guitarist Johnny A. uses the similar thing, IIRC...and there's a tradition for it going back to early blues/rock records. The 'neat' 3 piece standard in a lot of records...and how it would sound in front of the stage to a listener. Not a problem for me.
Like the recorded sounds very much.
All good, so far.
But, yeah, the feel plods on. There's a glaring opportunity to do a couple things...double the time for a section or two...or change the drum feel...take it from a strut to a roll...have a guitar orgasm in the last third........or swing it, as suggested. Or all the above. Something to build dynamically, bring the story to a new chapter with every new cycle...then outro it per the intro cycle. Looking to maintain interest...and build excitement....then close the book, as it were.
Only one other nit: The close of the cycle goes F#7#9 / E7#9 / F#7#9.
That wants to STRONGLY [conventionally] resolve to B7. You take it from F#7, and resolve back to the E7.
That's kinda weak...and uncomfortable...but it works right up until the resolution to E7.
Two suggestions:
The way I'd handle it is to resolve to B7 for two bars...play a nice thematic lick or two, and then , naturally, comfortably resolve back to the E7...and continue on. You'd have a nice little quirk, and recurring theme, and take care of the weak resolution all at once. You could even record the sections apart from the rest, and edit the sections into what you got.
Or you could play the cap of the cycle [ E7 / F#7 B7 ] to get the ear ready for the trip back to E7...without doing anything but editing-in the changed note and chord in the bass and guitar.
But that still leaves you with an arrangement that says what it has to say in the first cycle.
As it stands, it'd be a great 30-second floor for commercial application. But it's not a 'song'.
And, in addition, one of the things you could do to make it a genuine 'song'..in the tradition sense...is to develop and play a thematic melody in the first and last cycle...something memorable, before wandering into the very nice noodling likkage. Something for a listener to glom on to. Convention, with an important purpose.
But, again, love your playing and recording skill!
