How fascinating to discover this rather wonderful band!
I happened upon Alien Heat because... I used to be in a band called Alien Heat as well. This was way back in 1989 and 1990 in Exeter, England. We were perhaps somewhat more raucous than the Finnish Alien Heat, and perhaps spiritually we were not so far apart as the North Sea and two decades might make us.
If you would like to listen to Alien Heat from England, there are some pages at http://www.wudrecords.co.uk where you can stream audio, read lyrics, giggle at photos, read stuff about the recordings, and so on.
