My coverband recently changed from rock/pop covers to more rock 'n roll, soul which suits us much better. Big guitar riffs, aggressive, swinging and catchy. We love the contemporay act Vintage Trouble, but have trouble finding similar groups. Any ideas?
Recent favorite is the 2012 Simo album.
Weed through the Doyle Bramhall II catalog. And, seriously, Meshell Ndegeocello.
There are some Afghan Whigs/Twilight Singers tunes that are very soulful despite their generally harder edge.
Modoc is a little more twangy (for lack of a more fitting label) but they're nice.
Of course, there are also some Black Crowes/Marc Ford/Cry of Love songs that would fit what you're talking about.
