Burnin Red Ivanhoe was
formed back in 1967, and that makes them one of the first Scandinavian prog
bands. Their style was quite original from the start, blending jazz-rock with
R&B, blues, psychedelia etc. their debut from 1969 (double album) M 144.
Most of Burnin Red Ivanhoe's albums have that certain Scandinavian touch,
similar to early 70's prog groups such as Wigwam, Culpeper's Ochard
and Tasavallan Presidentti. In 1971, the band released the album WWW,
which is probably a good place to start, as it contains some of their most
progressive and interesting work. The self-titled album they released in 1970
(another gem!), also contains the track "Secret Oyster Service", and quite soon
after that, a new, even more jazz-orientated group was formed, called Secret
Oyster. Burnin' Red Ivanhoe was disbanded in 1972, although they released
one more album in 1974.
