In this trio's traditional configuration, Grdina also reminds me of Bern Nix from Ornette Coleman's electric phase. It's interesting how that approach is reflected when the switch is made to the oud. "Renunciation" begins with a long, freely improvised section before moving into a more classical Arabic-sounding resolution. This reveals not only the malleability of this group but some common ground between the musics in question.
As Grdina's trio moves between these two genres, the ear is presented with a mix of the straight ahead ("Albert The Monk"), Arabic classical (the beautiful title track), and the more out-there ("String Quartet #6"). It's quite amazing to hear how natural all of these styles feel when presented together.
John Cage was right. It's not necessary to have inner knowledge of this (or any!) music to appreciate it. One listen to Think Like The Waves and you'll just know.
