I have to agree, I'm not hearing much at the sides either. I agree that the bass is getting lost in places and that says to me that either the compression isn't quite right or there are some frequencies being masked. I am listening in my iphone and can't tell if the bass is lower than the kick drum or vice versa in terms of frequencies.
If I was mixing this (but I have to say that this isn't my usual style of music, tho I love the vibe) I would add some bottom to the bass and maybe accentuate the upper mids to bring out the tone a bit more, as it seems to be overwhelmed a bit by the ambience of the drums and the volume of the cymbals....but...saying that... It sounds like its meant to be... A live recording.
Please don't take my comments too seriously, I'm analysing this as an exercise for me to help learn the art of mixing, so I'm interested to read about the eventual outcome plus observations from those that know much more than I.
Nice sound, would come and watch you.
