Need to listen to Hyeana; I guess I was always put off by a couple of disparaging remarks made by Robert about the strings etc.
I don't own the Ten Imaginary Years book (oficial Cure bio 1976-1986), but I seem to remember Reading about him not being very satisfied with the keyboards masking his guitar parts a bit too much.
Besides, he didn't get as much credit as he'd like, and that, for a second time, because he wrote or co-wrote at least one song from Kaleidoscope ('Hybrid', and correct me if I'm wrong, but I seem to remember him claiming his involvement in 'Christine').
Well, it's not a bad album. It has its flaws and Robert probably hears 'em more than we do. 
I guess he saw its potential and wasn't too happy about the result. ("Out of the 10 songs finally chosen for 'Hyaena' four are good and six are boring" is what he said once.)
Must be that six songs were his, but he got no credit for that.
One is certainly 'Swimming Horses', which he as good as rewrote and turned into 'Six Different Ways'.
Interestingly, there's a funny number of Banshees/Creatures songs that have something to do with The Cure... or in reverse.
In 1987, the Banshees released the B-side
'The Whole Price Of Blood' -click to listen-, containing a previous recording of Robert on sitar.
Later on, in 1998, The Creatures released the song
Pinned Down -click to listen-, which... has a riff that is suspiciously similar to 'M'.
And in 1999, The Creatures released the song
Exterminating Angel -click to listen-, which ressembles Wailing Wall more than a bit.
Finally, in 2008 The Cure released Sleep When I'm Dead, whose bassline ressembles quite a lot the Candyman bassline (Robert said it was a "Head On The Door outtake").
Candyman -click to listen- was recorded by the Banshees in 1985, released in 1986. It's in the Tinderbox album, which I've always found it has some vague similarity to Distintegration, to some degree (and it has a 'Lullaby', too, although the Banshees 'Lullaby' is just a B-side -a very good one though).
Curious, isn't it?
I listened to it around the time I made that post (or a bit before) and enjoyed it. And that article from post-punk I linked is good, they're right: Robert's guitar work on "Blow the house down" is amazing. 
Indeed it is.
Click here to watch a live recording of the Banshees in 1984 (Running Town, Bring Me The Head Of The Preacher Man, and an incomplete Blow The House Down).
It's the only time I've seen Robert play his famous "fishbone" broken guitar.
The three of them sound rather different from the album versions btw.
