Here's a band that just crossed my radar. They're called 
The Pollies and they invoke all kinds of classic rock music with their soulful harmonica, roots-y growled vocals, reverb-y slide guitar and solid back beat. Their album is called 
Where the Lies Begin. Unsurprisingly, they've been touring with 
Alabama Shakes.
"Song For Carter"
"Something New"
You can check out their whole album, and buy it for the always reasonable $5, 
here.
