Ijereja is several things at once; it’s a fascinating exploration of the processes of composition, and where these processes begin and end (with the composer, the musicians; even the listener?) and an examination of music as a uniquely boundary-crossing phenomenon, belonging simultaneously to time and space, to the composer, performer and audience. It’s also, somewhat anomalously, an album, a recording consisting of one fifty minute piece, sometimes described as an opera, but comprised as much of speech, ambient noise and found sounds as of (somewhat minimalistic) music.
