Anyone know of a band called Tiistai?

I came across this band around a year or two ago, and they’ve instantly become one of my favorites.

The only information I’ve been able to get about them is that they existed from 1984-1987, and they were formed in Oulu. They released two 7" and one LP, which is avaliable on Youtube.

My favorite track from them is Ansassa. Very unique post-punk sound. https://youtu.be/yttzG0UUVWc?si=m6HItYoaNM1DEBFm
