Music On Walls spotted some "Blues On Wood", with these great street art installations by Joe Iurato. Indeed, some pieces of this project (see whole project here), consisting of small wooden figures, are paying tribute to the Blues.
American The New Jersey-based artist Joe Iurato carves and paints each one before throwing them up in appropriate urban environments. "While some are rather tongue in cheek, others add a level of social commentary to otherwise conservative scenes". - Highsnobiety
