Interactive Poll XIII - Surprise, surprise

What I mean by this is these moments when we come across some music that we don't know that totally surprises us. Maybe because of its quality, and we didn't know the artist before and heard it on radio or TV randomly, maybe because it is a way of doing music that we couldn't have imagined before, or maybe also because an artist who we knew already did something totally different from what we expected. That may be good, but it may also be a shock at first - you can propose something that surprised you at first in a bad or in a "I don't know WTF this is about" way, but of course this poll is about great music, so in that case I'd assume that you later managed to get into it. It may also be something that you heard in a totally surprising setup (I was stunned getting to know Swans in a local bike shop in London and a few days later when I went there to get my repaired bike back, they played some other phantastic music that I hadn't known before).

So musically this can be very eclectic, and of course you don't need to necessarily try to surprise the others by your choice... maybe something came completely out of the blue to you in 1990 and developed into a style that by now everybody knows... doesn't matter, it qualifies if it has been a surprise to you.

Optimally suggest the very song that surprised you (but I'll bend this rule a bit for my own, see below, so there's some room for interpretation).

We stick to the "not listed on PA" rule. Everybody can nominate one and we got into the habit of posting alternative selections, which tends to overload me, so maybe stick to one plus one alternative... but obviously eventually everybody will post whatever they feel  like posting anyway...

I'll wait for nominations until end Friday and then on Saturday will start the poll. As usual, everybody has three votes; and don't vote for your own suggestion.

According to mathman's great interactive poll links thread, this should genuinely be poll number 13. If that's an issue with you, tough luck. I heard that the University of Bologna  (scientists of all people!) opened their Departments of Psychology and Statistics on the same day because before they had twelve, and at no time they wanted to have exactly 13. Given the general confusion, I could've easily hidden the true number, but no, live with it!

Thinking about what I propose, I realised that actually quite a few of those that I had already posted or mentioned had such a surprise effect on me - Astor Piazzola, Rokia Traore, Scorn... all came to me unexpectedly and I hadn't known such music is possible and can work... Here's another big one. I heard them playing this in a music TV show in the early eighties that I wouldn't watch regularly. I didn't even think before that the show was very good, but then came up Swiss duo Diethelm/Famulari and absolutely gobsmacked me with a brilliant performance of something I had never heard before. They did this thing live with guitarist Thomas Diethelm using a delay to repeat his own phrases and playing duo with himself plus drum machine plus the stellar keyboard playing by Famulari; sounds much more than two people at the same time, doesn't it? But it really sounded pretty much like this live.  Actually I slightly cheat here because if I remember it correctly they played three tracks in the show, and this was the second one. The first one already surprised me but this one was even better. Actually they should be on PA but I'd suspect hardly anyone here knows them (apparently the album was a hit in Chile).

Very curious of what you come up with!
