This is a split with one rocker on each side. Martin Savage Band performs a loose, trash rock version of “Thunderbird,” a ZZ Top cover. It’s a mid-tempo rocker with a swing in the chorus. Mary’s Kids’ “Esther Be the One” is also a ZZ Top cover. This song rocks along the 12-bar blues formula with messy back ups and a jumpy organ in the mix. Both bands adopt the covers with a trash rock swagger. Good rockin’. –Billups Allen (Human Audio Recordings, humanaudio.bandcamp.com)
