No I kinda cheated here. Maylene &The Sons Of Disaster technically have named each album I, II, III, and IV, so I can't use it for "M". However one might also argue that this is a form of having a self titled album, so that's what I'm going with.
Maylene is a really interesting mix. It's Southern Metal, but not. It's got banjo, slide guitar, and all that kinda of stuff, so maybe you could call it Bluegrass Metal? I don't know really.
It's a really cool sound though and I'd say you should check out the following tracks.
Waiting On My Deathbed
Last Train Coming
Step Up (I'm On It)
The Old Iron Hills
No Good Son
