I just wished that Primus had scaled down a bit the total weirdness of Brown Album's production, but I still appreciate it a lot. I really like all the Primus albums (I consider Chocolate Factory a cover album), including Anti-Pop. Brain made a great work on those albums, he just didn't fit so well in Primus, like Stadler said.
Maybe you already know, but Jay recorded the demos for many of the songs on Frizzle's Fry and you can hear the difference in Tim's drumming approach on Frizzle and Sailing Seas and I guess it's because the absence of demos with Jay on Sailing's songs.
