Weasles - yeah I like this one more than you but I can understand how you feel on it. Does have a rough odds and ends feel. I dig "Mama" quite a bit. It's a catchy groovy tune. I also like "Toads Of The Short Forest" because the wah'd guitar makes it sound like a bunch of toads creatures in a forest somehow and "Get a Little" has some nice guitar jamming but i know you're not into that kind of thing.
Don't remember if I heard that Amon Duul II record but Yeti and their debut are great weird shit that I've been meaning to revisit myself soon.
Barrett - yeah kind of just skipped it for a long time myself until listening more a few years ago as well as some of the earlier Pink Floyd stuff like Atom Heart Mother and Obscured By clouds, stuff I haven't heard as much as I should have. Barrett has some nice songs for sure and it's slight but charming. I liked pretty much all of it.
