Query: Their last Great Album

Slip it In I would consider Flag's last really really really good album they released. I found Loose Nut and In My Head (get it? Slip it in - that loose nut thats "In my head"?) to be good, but too slick and unfocused. They veered way too closely to a generic "metal" sound (not that metal is bad but it just seemed to be a fake thrash style that was almost poppy) and just didnt have the craziness of earlier efforts like this one. It starts with Slip it In and concludes with "You're Not Evil" and is filled with crazy, almost semi prog sometimes in 3/4 thrash punk doom metal free jazz sludge! (quite a mouthful that one). All the instruments sound equal in volume (and that includes ol' Hank who had a problem being heard on the following two) and the crash and burn zaniness of this album is- here it is folks- TIMELESS. Buy it, its awesome.
