I have seen this on a few shmoo lists, what's it like?

lp: Joanna Newsom -Milk-Eyed Mender
np: Massive Attack - Protection

Others here (chase, I think) can describe this better and in their own words, but I tend to be terrible at that, so here's what AMG says;

The Australian indie pop octet Architecture in Helsinki hails from Fitzroy, Melbourne, and counts multi-instrumentalists Cameron Bird, James Cecil, Gus Franklin, Isobel Knowles, Jamie Mildren, Sam Perry, Tara Shackell, and Kellie Sutherland among its ranks. The band's musical arsenal is even bigger than its roster, featuring instruments as diverse as analog synths and samplers, glockenspiel, tuba, clarinet, and recorder along with the more predictable drums, bass, and guitar. Architecture in Helsinki began playing in 2000, crafting a mix of indie, electronic, and pop that they recorded and occasionally performed live. The collective began recording its debut album, Fingers Crossed, in 2002 in a variety of places ranging from beach houses to proper studios; Bar None released the album in spring 2004.

A lot of airy, sweet layers. I like it.
