just filler! the guitar is not a power tool,and playing it isn't an athletic sporting competition.even though this cd seems somewhat childish at this point in my life,in the 80's it would have lived on my record player.athough it lacks emotion in my opinion,i guess it's only supposed to be an out take cd and not to be taken too serious.if your looking for a fun cd,that sometimes can be funny this cd is worth your money,if your a 1st time listener to steve vai,and want to see a more serious side to his music,you might rather start off with david lee roth-eat em &smile,sky scraper,his 1st commercial solo release-passion&warfare,or whitesnake-slip of the toungue.
