Just an idea!!!

[Powerslave]

I liked the idea, since I could finally get one right without guessing (and making myself look silly), so I'll continue it, only with some more recent bands. Since some of these may be quite tough, I've added their nationality and 6 out of 8 correct is all I'll require. Each band is on AM, however.
Also, each lineup is current or from the most recent album.

1. AM, RO, NDV, DM (American)
2. NM, MP, PT, RS (US/UK/SWE--sheesh what a giveaway!)
3. JB, J-FD, YJ, DJ, FD (Fr. Canadian)
4. C, SB, PA (British)
5. MR, BD, JB (American)
6. GF, DF, UP, SL (Swedish)
7. RS, IS, CN, MP, JM (British)
8. FL'E, DL, AF, SS (French)

Best of luck. Clues will be provided if needed in a later post.
