Somehow I agree with all the posts above
They are usually boring, More than a couple is pushing it etc. etc.
It would take true creativity both vocally and production wise to pull it off successfully for a whole album
The other thing is (present day) not all drumless beats are created equal, That's why Madlib gets less flack than Al
His drumless shyt is often funkier/more soulful than Al's shyt with drums (see Freestyle S**t for example)
+ there's the more layered shyt like some of Jay Elecs stuff
Generally dudes should give it a rest though, Get creative.
