I kind of liked almost the whole album the way it is - specially the first 4 tracks,and some of the last ones.I also liked the style of the guitar solos(reminding me some of Zappa's stuff).I also found a couple of relly good ideas in sudden changes.
I'd expect more colorful guitar sounds do (maybe some effects,or a guitar syntetizer...
It reminded me a lot of the music of the late 60s,early 70s,and this is a great reason itself to like it. :)
I'd rate it up to 8,5 stars,or points,or whatever,but I'll give 10 to balance the underratings.
