Nine Clues

Past the halfway point in Son of 20 First Lines Rides Again. Here are some clues for the nine which nobody has yet guessed.

2. From the current album by Scandianvian band who have recently become national heroes in their home country; there's even a set of stamps in their honour.

4. By the current kings of widdly prog-metal, from their last but one album,

6. A song by a 'Cod Irishman' allegedly inspired by an Arthur Machen short story

7. By a short-lived turn of the century goth-prog band (I think they did one other album) with a viola as a major element of their sound.

8. Current Scandinavian band who allegedly have some prog-rock influences.

10. Yet another bunch of Scandinavians, from the same nation as (2), but this song is in their native language. Currently on hiatus while they find themselves a new singer.

11. Even more Scandinavians, featuring one member of the neo-prog supergroup Transatlantic.

18. From the recent live album by an American bluegrass/prog/jam band.

19. Recent song by a bunch of Welshmen that wear their nationality on their sleeve.
