These two are nestled in between the Meat Pups and the Mekons, so this is a short installment.
Meat Purveyors - All Relationships Are Doomed To Fail (2002), "We Kill Evil," and "Hangman." The Meat Purveyors are an Austin institution of aggressive, punk-influenced bluegrass. This album and these two live tracks (both recorded at the legendary Yard Dog SXSW free shows) all kick mighty ass.
Medeski, Martin, and Wood - Combustication (1998). Organ-dominated instrumental music pitched somewhere between the 70s groove jazz and jamband rock. Not so bad, but not enough to make me seek out more.
