If Mostly Other People Do the Killing seems to be all about cleverness –mysterious band name, calling their fourth album Forty Fort, Impulse!-like cover art, pseudo-brainiac liner notes by "Leonardo Featherweight," a goof on jazz critic of renown Leonard Feather – well, there is that. Even those who profess to disdain jazz's avant-garde, into which school this certainly falls, may very well be sucked in by the sheer fun of it all. From the first track, "Pen Argyl," the quartet – Moppa Elliott (bass), Peter Evans (trumpet), Jon Irabagon (alto and tenor saxophone), and Kevin Shea (drums, elecronics) – makes it clear that as serious as they are, they're not all that serious.
