I'm looking for bands with a similar sound, and lyrical as the almighty B.L.S!

Have you checked out Pride & Glory? Personally think it is better than anything BLS has ever done.

I don't know how, but Mastodon always remotely reminds me BLS.

You might enjoy the band Orange Goblin.

Are you familiar with the well-known bands that are somewhat similar and related? Crowbar and Down come to mind as the most similar, but you might also like some of the stuff that's a bit less refined, like Corrosion of Conformity (start with the album "Blind"). Maybe some other stuff that has a southern feel to it like Alabama Thunderpussy, Superjoint Ritual, and Floodgate. Depending on what you like about BLS, those might get a bit away from what you want, but they're some prominent names that come to mind. They don't really have the biker arena rock feel that Zakk has, but the roots are there.

Will have to check these bands! Hails to u brother!
