The current band led by hard-core Austin honky-tonk singer Dale Watson, who performs at Martyrs’ on Friday, is called the Texas Two, a clear reference to the legendary band fronted by Johnny Cash in the 50s. In case that salute weren’t explicit enough, the group made its inspirations even more obvious on it most recent album, The Sun Sessions (Red House), released in October; it was cut in Memphis at Sun Studio, where Cash, Jerry Lee Lewis, Elvis Presley, and Carl Perkins all made their paradigm-smashing records. The session was relatively spontaneous—the group were already on their way to Memphis when they learned their gig there had been canceled. Watson called Sun and found out that the studio was available.
