I have Harakka Bialoipokku (aka B The Magpie) and Kätkävaaran Lohikäärme . both are very good especially the former. Great zappaesque horn arrangments over fusiony grooves. Gotta get more into his music myself but the albums are so hard to find here! Anyways, B The Magpie would make a great start.

Agree with Hugo, get the two he mentioned they are both awesome fusion albums with a definite Zappa feel. Also recommend Keesojen Lehto, Visitation, and Pihkasilmä Kaarnakorva as well. If you like those, look into his more recent stuff, its good too, although a bit slick sounding at times. Dunno if you've heard his Wigwam stuff, but all the albums he's on are good, with Fairyport being my favorite. Also, kind of obscure, but he also recorded an album in 1978 I think, under the moniker The Group. If you can find it, it is also a great fusion album.

Syzygy wrote: He's done some amazing stuff, kind of a Finnish Frank Zappa. The Mathematician's Air Display was released on Virgin in the late 70s and featured contributions from Mike Oldfield and Pierre Moerlen - I think it was also released with a Finnish title and may have been mentioned already. He's released an album every 3 years or so since, and everything I've heard has been excellent, although as some others have mentioned some of the later stuff is a bit slick at times.

Yup the album you are refering to was released in Finland as Keesojen Lehto, which I mentioned above, and is a great  recommendation there Syzygy.
