Black Joe Lewis hasn't mined the same success as fellow Austinite Gary Clark Jr. when it comes to riding the crest of retro-blues rock that the Black Keys and Jack White have helped to popularize. Perhaps it's because they've always represented somewhat of a moving target, their 2009 debut Tell 'Em What Your Name Is! largely consisting of James Brown vamping, while the 2011 follow up Scandalous found Lewis and his Honeybears delving deeper into P-Funk.
"Skulldiggin" takes the band even further left field, the crushing riff and claustrophobic production nearing 70's metal levels of heaviness. Electric Slave isn't out until August 27 (on Vagrant), so time will tell if this is a new direction or just a one-off. With Black Joe you never can tell.
