The prestigious Alligator label out of Chicago is renowned for its blues roster. With the exception of Mavis Staples’ ’04 release on the label and the injection of strong elements of soul into the blues of some of their artists (Shemekia Copeland, the Holmes Brothers, Curtis Salgado), authentic Chicago blues remains its mainstay. Southern Avenue – named for the famous Memphis street that leads straight to the Stax Studios – is a marked foray into soul country. While elements of the blues are present (Southern soul is, by definition, a component of Memphis blues), this is a soul release underlining the notion of ‘family’: Tierinii, Tikyra (“T.K.”) and Ava Jackson are sisters, while the band’s fourth member, guitarist Ori Naftaly, married to Tierinii, is clearly part of the family.
