No I haven't, but I just checked around a little and they do sound good. I generally prefer the stuff with vocals, especially when the songs are so strong like on Neon Golden. Is it just that you prefer music without vocals, or is it that you like "purer" electronica? The field you label as indietronica is one of my favorite nowadays, with bands like...
The Notwist
Laika
Stereolab
Manitoba
Múm
Lali Puna
Dntel
Four Tet
Mouse On Mars
The Postal Service
Solex
Broadcast
Hood
Nice musical taste.
Here are a few other to check out.
Mice Parade
Arab Strap
Her Space Holiday
Monade
The High Lamahs
Barcelona
Enjoy!
Do!
