Ah man you for sure need some Clutch in there somewhere, unless I overlooked it on your playlist? Might also check out the off shot band by Clutch band members as a side experiment called The Bakerton Group. The Clutch band members did this side band for a short while to see how fans would react to a change in musical direction, and as they say it is all history now man.
Check the artist pages out here and the top songs from both artist pages.
The Bakerton Group, sadly only the second release by the band El Rojo is available. The bands self titled debut release is not currently available on the Spotify service but it is rather good, the debut release is a spacey stoner rock kind of thing, check it out if you can find a cheapie second hand CD copy of it somewhere.
