Who is Piäsky?

One of the founder members of influential Finnish hardcore band Terveet Kadet. I can't find any record of any other name for him. He's just Piäsky everywhere you go.

Anyone able to have any success?

[fi.wikipedia.org] https://fi.wikipedia.org/wiki/Terveet_K%C3%A4det#Historia says Markus ”Piäsky” Saarenpää, though the citation refers to a page for a Markku Saarenpää

[iswcnet.cisac.org] http://iswcnet.cisac.org credits the band's song Anno Domini to Markku and Veli Matti, so Markku is correct.

Many thanks -- that sorts out a lot of potential tree.

What about Peedro a.k.a Petri?

Petri Rankka looks to be the guy. I've added the years of the albums that these songs seem to be from:

AHDISTUS (2009)

AEIJAELAE VELI MATTI
KINNUNEN ILARI JYRKI
LEINONEN MARKKU LEONARD
RANKKA JUHA PETRI


AWAY (2000)

AEIJAELAE VELI MATTI
AEIJAELAE (TEOSTO) TIMO
KORKALA PETTERI MICHAEL
VALANNE MIKA VALTTERI


BELAJA SMERT (2000)

AEIJAELAE (TEOSTO) TIMO
KORKALA PETTERI MICHAEL
POHJOLA MIKA ANTERO
VALANNE MIKA VALTTERI

Sorted. Thx.
