Originally released as a 3 CDr set on Inyrdisk to commemorate 30 years of If, Bwana, and now available on manufactured CDs, this triple disc gracefully spans 3 and 1/4 hours of riveting musique concrète and refined experimentation from Al Margolis. These recent recordings come to you re-mastered and repackaged from the self-released tapes sold in a nearly invisible edition during a brief tour, sub-titled within Thirty as Blue Two, Green Three and Yellow Four. Thirty captures If, Bwana championing familiar territory with haunting long-form drone compositions such as Organ Life(less), Massed Roses and Forks, Waves, Bees and forging ahead with new sonic focus into the infinite worlds found within bassoons and voices. From an Avant Music News review by Dan Barbiero:'In the course of its three-plus hours, Thirty reveals some of the major tropes and favorite sound sources Margolis has explored over the years. One of these is tropes is the creation of variably dense drone music out of looped, stretched or otherwise manipulated samples of instruments or voices. A good example is 8 Notes, 16 Speakers, x Players, which begins with single stabs of a piano note which gradually multiply and expand in pitch until evolving into cyclical waves of sound that give the impression of a slightly detuned tamboura. Forks Waves Bees is a more conventional, thick drone piece, while Diapason 40 takes what sounds like stretched horn tones and layers them into long, dissonant chords.'One of the hallmarks of If, Bwana is the enlistment of acoustic orchestral instruments and human voices into the service of electronic experimentation. James (Leuven) Piece constructs a virtual string ensemble from spare samples of string instruments; Al, My Bassoons elongates the notes of a bassoon - an instrument that Margolis returns to again and again - until something resembling an organ dirge results. Ross Bassoon 2 transforms the bassoon into a complex drone, as does Kat Lib Bday Bassoon. At the other end of the spectrum, Roe Girls 2 is a sparse, space-filled piece in which female voices singing three notes are overlapped in and out of synch. Pushing the exploration of voice into more radical territory, Secular Totems is a collage of fragmented vocalizations that are neither speech nor song, yet somehow seem to convey emotional states in a dramatically direct way.'Contemporary work at its deepest, and a must for any If, Bwana fan.
