scorchersi'd like to qualify my earlier statement by saying skynyrd and the allmans really threw it all away and SUCKED after awhile, as most of you will probably agree. greg allman became a cartooon, with the solo album with Cher ????
As far as more recent southern rockers i'll have to mention Jason & the Nashville Scorchers (later just jason & the scorchers). More southern punk than southern rock, they disappeared pretty quick, but they were great in the early to mid 80s, got an album-of-the-year award or something like that from Rolling Stone ZIne before disappearing, they were especially good live.
as for zz top, i loved them up to tres hombres. i saw them open for skynyrd at a redneck 3-for-one special outdoor concert in nashville more than 30 years ago ... i think marshall tucker was also on the bill but i don't remember for sure... it was at the speedway, on a blistering hot july 4th weekend ... one of the worst concerts I've ever been to with the rowdiest, most obnoxious and drunken fans ever, with flying beer bottles and the stench of BO and vomit completely overpowering the music. Yucch. Thankfully moved to california shortly after that.
I am also not that impressed with drive by truckers, but have only heard one of their albums.
