I've never heard of that, gonna check that out!
I think my favorite side project I've encountered so far is definitely Sunset Rubdown. They put out 2-3 very solid albums. I've also heard Swan Lake and Handsome Furs. Frog Eyes are great too, but I'm unsure where they overlap in terms of personnel.
Here is a chart that may contain other side projects, but there may be a few weak links (like one album of shared credits).
I can't say I've been listening to anything similar lately.
But here are some random stuffs I have enjoyed recently:
Neil Cicierega - Mouth Moods
Aphex Twin - Collapse EP
Sophie - Oil of Every Pearl's Un-Insides
Converge - The Dusk In Us
Animals as Leaders - The Joy of Motion
Also, on Wolf Parade.
Their first album is really great. It's an art rock album with a lot of forward momentum. Listen to this one first if you are just stumbling on this thread!
With
At Mount Zoomer they really opened up their style, and they get great results on a number of tracks, but it's too ambitious to not be bloated with filler. I think I admire the album more than I enjoy listening to it. I was obsessed with it when it came out but I've grown to prefer their debut.
