This week, I’m joined by Frank Hannon, guitarist for Tesla, for a deep dive into the songs that have defined the band’s nearly 40-year career. From raw, blue-collar hard rock to acoustic reinvention, we trace how Tesla’s music has evolved while staying true to its roots.

We also dig into: the secret behind the lasting impact of their debut album Mechanical Resonance; how Five Man Acoustical Jam helped spark—and legitimize—the unplugged movement of the ’90s; the way shifting musical trends shaped 1991’s Psychotic Supper
