Bassist Moppa Elliott’s septet, Mostly Other People Do the Killing, is a group of jazz conceptualists (a previous project recreated Miles Davis’ Kind of Blue, note-for-note), knowing historians and virtuoso wackadoodles for whom humor definitely belongs in music. The centerpiece of Loafer’s Hollow is a suite of five pieces inspired by specific passages in some of Elliott’s favorite novels. “Bloomsburg (For James Joyce)” mirrors Ulysses’ orgasmic conclusion and “Mason & Dixon (For Thomas Pynchon)” quotes Cannonball Adderley, among other citations. It’s great, goofy fun—witty, sophisticated and virtuosic at once, with a swing-era imperative to entertain.
