Pondus's Myrornas Frammarsch (1979) and Myrbein's Myrornas Krig (1981)

Both bands made but one album each.  Beginning with Pondus, who present to us an all over the place varied mix of folk, rock, and fusion-- and that's by no means a complaint for us of course, just for the music industry (RIP), like Kebnekajse (I refer mostly to their III album) and Samla Mammas they use acoustic guitar and folk to spice up the electric guitar passages.  One of my favourite all time straight up songs taken from a progressive rock album, shoulda been a hit in the seventies, is the stunning song Livets Låga:





I love the casual melancholy of the melody and the way the chord progression builds upwards in a climactic way till the flute plus electric piano take it back down again for another verse.  God forbid we should ever come across such a well-crafted beautiful song again written today.

The album closes out with a masterful guitar-based fusion lava outpouring called Flumlåten well worthy of Mahavishnu John McLaughlin:





Turning our attention now to Myrbein (info here), let's start with the second track, called De Fyra Stånden.  Here we have echoes of co-nationals Blakulla, prog masters Kultivator (recently reissued to CD with some very disappointing bonus tracks), with the heavy grinding fuzzy electric guitarwork:





Most of the tracks feature grinding electric guitar, always a difficult endeavour in progressive rock, here not always successful, but often enough for us to walk away happy.
The album title has a wiki entry here, btw.
