We’ve been posting songs all summer by Screaming Trees drummer Barrett Martin’s instrumental collective Tuatara, the band that recorded NPR’s All Songs Considered theme song among other accomplishments. Here’s another one. R.E.M.’s Peter Buck, who shows up throughout Tuatara’s forthcoming Underworld, guests on “Even Demons Fall In Love,” a moody jazz fusion number that interpolates “My Favorite Things.” Underworld, Tuatara’s first album in six years, was mixed by grunge-era Seattle scene fixture Jack Endino, and Pearl Jam’s Mike McCready also guests throughout. It’s wild to think these jazz-fusion dudes are the same people who were helping to define the sound of underground rock 25-30 years ago, but times change and so does taste. Listen below.
