I think mine might be Future Days. Blissful stuff.
It's probably the one I listen to all the way through the most, although it is hardly a 'typical' Can album.
The other contenders are obviously Tago Mago and Ege Bamyasi, both excellent although hardly easy listening (although that's obviously not the point)
I have a lot of affection for Soundtracks, which is an oddity of a record really but really great throughout.
but now I might say Ege Bamyasi
Malcolm Mooney was fucking great in a deranged kind of way
As mentioned before it can be listened to from start to stop and doesn't have any crazy vocals, some of Damo's "vocals" on Ege Bamyasi are a little too much for me at times, I actually think it spoils the music at times.
Got Soon Over Babaluma for Christmas and have played it a fair bit, another great album.
i think its my fave at the mo.
I drumbeat 21 hours a day, I'm in love with my girl, she's away... (etc)
But really, they're all awesome up to and including Flow Motion, and the later albums have their moments.
...but I'm a sucker for Monster Movie.
It's the one I go back to most often. It has the right balance where I can listen to it and be ingrossed or leave it in the background and it still sounds great. It's not the best, but it probably is my favourite.
because it has the 14 minute version of Mother Sky, which is the best Can track of all.
