I was introduced to this band by @melissapulo who put one of their songs on a mixtape (or CD in actuality). The song on the compilation was actually "Replicate", which is also brilliant!
Whereas Replicate is puzzled, fidgety and nervous, Tunguska is warm, fuzzy & epic. Spacey verses, and a comforting chorus with lashings of sax thrown in too.
There are loads of little sounds & things going on in this song, and all of them are fantastic.
