Melding elements of indie rock and blues, tonight (09.28) Brooklyn’s The Disappointment welcomes their debut EP, “Damn Righteous” with a show at Rock Shop. With their witty lyrics, vocals dripping with drunken swagger, and themes that ooze with booze, The Disappointment insert themselves in the rich tradition of rocking American songwriters inspired by roots music. “Where’d The Drink Come From?” starts the buzz with synths the creep along and crescendo into an impassioned chorus. “The Prince and the Playground” chugs along and narrates a fantastical ode to their hometown, and “Sharp As Knives” floats with syncopated hihats and smooth guitars while “Technically 17” (streaming below) centers around humorous verses. The final track, “The Best Pereson of All Time” returns to the opening sonic motif of haunting progressions. Joining the Disappointment at The Rock Shop are Chainwave, The Archive, and XVSK. Doors at 8pm, 21+, $10. – Meijin Bruttomesso
