It is a stretch, but the last part of Sweet Black Angel has an "island sound", at least - with the marimbas and the groove there. It's not pure reggae, though
Here's a post I wrote about this song some years ago.
On Exile On Main Street we are literally spoilt for choice for exceptional songs and Sweet Black Angel is certainly one of them.
For starters they have created here an original music form – part country blues, part calypso, part hillbilly folk – that is quite unique. Usually you can tell right away who or what has inspired a Stones’ song but this is most definitely music of their own devising and a great example of the wonderful melting pot of primarily roots American music that is Exile On Main Street.
It’s also one of the most political songs the band have ever written – almost certainly Mick’s lyrics and this black consciousness inspired by his recent affair with Marsha Hunt.
Was there any need for the 'n' word in the song? I'm not so sure and I doubt whether, written today, Jagger would have used it. It certainly doesn't add any gravitas to the already controversial lyrics.
And despite the heaviness of the lyrics about the murder rap on black activist Angela Davis the music has an incredible warmth, like a campfire song with the sweetest sounding acoustic guitars, that amazing percussion including Mick’s harp playing, a jew’s harp, scraper and Charlie’s cowbell. You're immediately transported to another place - for me it's a backwoods Louisiana bayou with frogs croaking, crickets chirping and a jug of hooch being passed around in the sweet summer moonshine.
And then of course there’s Keith’s backup singing. I don’t think Keith was ever in better voice then on Exile, those high register harmonies are all over this album and here they lend the song a sweetness. And let’s not forget that beautiful, underlying marimba playing that comes in just towards the end played by Amyl Nitrate, otherwise known as Richard ‘Didymus’ Washington, from Dr John’s band.
