Rock ’n’ roll reverence and album-oriented adoration are both big in Music City. While band scene kings The Long Players have made their mark taking on classic rock’s most venerable LPs, Mayhem — another album-covering ensemble led by drummer-at-large Jerry Pentecost — often opts to take on more left-field rock and pop opuses. Whereas the LPs might tackle Purple Rain, Mayhem faithfully adapts The Purple One’s less accessible Controversy. But tonight Pentecost & Co. encroach on LP turf, performing not one but two of Tom Petty’s outright classics — his 1979 breakthrough Damn the Torpedoes, and his 1989 mid-career hit parade Full Moon Fever. Each is an album The LPs have already conquered. But each is also an undeniably timeless effort, replete with FM staples such as “Even the Losers,” “Running Down a Dream,” “Refugee” and “Free Fallin’ ” — outright classics that never make for a bad live listen. With any luck, it’s only a matter of time before ’90s-exclusive cover guys My So-Called Band try their hands at Into the Great Wide Open. So, any takers for the The Last DJ? … Anyone?
