Glenn Branca
I could say just about everything that has hit the mainstream since the late 1980's has been absolute shite because, well, it has been. But that's quite a wide brush, and it's difficult to be specific since nowt stands out as being more shite than the rest of it.

However...

The single most awful thing in my record collection is an utter pile of crap by Glenn Branca entitled "Symphony No 6". Now you may wonder how I came by this. The guy who reviewed it in Q Magazine said it was absolutely wonderful, so I figured WTF, let's give it a go.

So, I get's it home, fire up the hi-fi, put it on the turntable, and hit play. This is basically seven guys with guitars. They pretty much spend the whole of the first side playing "da-dum, da-dum, da-dum, da-dum" for 30 minutes. Turn it over, and the other side is more of the same. Now I can handle strange stuff. I can deal with some of Frank Zappa's worst excesses, and I rather like Sheila Chandra's "AboneCroneDrone" in which she mucks around with drones for 40 minutes, but quite what the reviewer saw in what Branca and his buddies were playing, I really don't know.

On the subject of reviews, my favourite was one which appeared in one of the newspaper-type music publications (NME, Sounds, etc... not sure which one it was). It was of a single released by Andrew Ridgeley and it basically read "Inside every one of us there is an Andrew Ridgeley waiting to come out. Fortunately, most of us take a dump every now and again and it's taken care of."

On a similar tip...
NME's review of George Michael's Listen without Prejudice Volume 1:

Listen without speakers.

Sweet Jesus you're right!
Just checked out old Glenn on Spotify. I thought I was open minded but f*ck me this is just a racket.

Hmmm...
I can't speak for the piece you criticise as I don't know it, but I feel you're being a little unfair. What did you expect from an avant-garde composer who specializes in repetitive drone pieces for numerous guitars?
He may not be your cup of tea but Glenn Branca is quite an important figure in the post-punk/no wave landscape, his early work especially (try Lesson No.1, it's fairly accessible). At various times his ensemble contained future members of Sonic Youth and Swans, both bands who took major influence from him.
Sorry to rant, but I feel you're wrong.

You feel he's wrong for not liking someone?
Don't be a cock.
