I really like the SRV intro, although maybe a little too much of a nod towards "Scuttle Buttin'", however the rest of the track is suitably different so I think it is fine
The horns are working well for me and I love the stabs
The rhythm of the drums sounds great to me - just a bit of work to do on the sound/mix of them but that will come with time
I would lose the horn playing the melody line as it does sound a little "synthy"
Overall I really liked the track and enjoyed the familiar sequences but with a different twist
Great stuff!
