> You might find Riverside Plaza (aka Cedar Towers) in Minneapolis an interesting bit of colorful Brutalism.

The colour does remind me a bit of a Mondrian, but I think it should be removed from the earth just as one would remove mercury-contaminated soil.
That's not Brutalism, that's pure classic modernism. Very Corbusier.
I'd say it's both. If you get away from the heights and walk around the base of the buildings, it's totally Brutalism - straight-up shaped concrete, nothing to decorate but the shape itself. It's also remarkably walkable and sociable. It feels like a space rather than an obstacle. (I credit part of this vibe to the Somali community, who are strongly self-policing and don't tolerate dangerous gangs of young men in their space)
Today, they're populated almost entirely by Somali immigrants, which really makes for a particular Third-World feel that's not visible from photos. Cedar-Riverside is a lively and densely populated neighborhood, and the towers definitely dominate.
