Minutemen. Great call
Mike Watt is one of the best bassists ever IMHO (post Minutemen Firehose - If'n is a brilliant album)
Yeah, I only very recently discovered them and started digging in, so now I have to get ALL their records (this will take some time as my wishlist is long and my funds are limited). They were associated with the American punk and hardcore bands of the 80s, which I fully understand, but their musicianship and range is much deeper I think. I saw somewhere how they were very influenced by Wire (Pink Flag, I'll just mention here, one of my favourite albums. Also got Red Barked Tree recently, from 2011, and it is immense) and you can see that in the track lengths/structures etc.
Still only just edging my way in with them, can't wait to get more stuff - funds permitting.
