An Under Cover Weekend: The '70s at the Bluebird, Saturday, September 6

LOGOS
In reality: A classic-rock-leaning trio that has opened for Todd Rundgren and other KSHE icons — all before two of its members can even legally drink.
Artist covering: Rush
Why this will work: The youthful band has the gnarled, wizened riffs and helium-filled vocals needed to handle Rush's oeuvre — and an uncanny ability to drift off into outer-space prog-land without floating away.

Rush, "Tom Sawyer"

The Dock Ellis Band
In reality: A wistful, whiskey-soaked sextet that takes its cues from vintage country blues and pedal-steel heartbreak.
Artist covering: Alice Cooper
Why this will work: Dock Ellis co-vocalist Jesse Irwin possesses a 1,000-megawatt smile and a magnetic, charismatic personality — two things that also drive Cooper's horror-rock shtick.

Alice Cooper, "School's Out":

Jon Hardy and the Public
In reality: Springsteen, Gram Parsons and Spoon all rolled into a roots/Americana/power-pop package.
Artist covering: Randy Newman
Why this will work: Like Newman, Hardy is meticulous about his lyrics and arrangements — and his crack backing band the Public is talented enough to tackle the intricate instrumentation.

Randy Newman, "Short People"

MP3: Jon Hardy & the Public, "Trouble"

The Blind Eyes
In reality: A mod-pop trio whose Jam jones is rivaled only by its love for early Elvis Costello.
Artist covering: Uh, Elvis Costello
Why this will work: Gravelly co-vocalists Seth Porter and Kevin Schneider out-Costello the bespectacled one, while the group's taut riffs and rhythms are pure This Year's Model.

Elvis Costello, "Pump It Up":
