The Unrepeatable Quartet consists of Chris Dadge on percussion, Ellwood Epps on trumpet, Jack Wright on alto and soprano saxophone, and Scott Munro on trombone, viola, and electronics. Dadge also runs Bug Incision Records, and each of them also work in a host of other ensembles. This improvisation session was recorded at David Ferris' house in Edmonton in 2012 and now you can experience it as if you were there - and by the time you're done, you'll wish you were. This is amazing improvisation with lots of energy and variety. I get the sense that 'unrepeatable' is intentional ' they would have a hard time doing this the same way twice. This is not all in your face; there is a good mix of dynamics and quiet passages that keep it all interesting. One thing is certain ' they would be amazing to see live. A lot of the jazz I get to review doesn't really push the envelope much; this one does. Needless to say, you won't hear this on your local 'smooth jazz' station (which is a shame). Still, these are highly skilled musicians who manage to make order seem like chaos, which is no small feat. If you like experimental jazz, you need to get this. This album weighs in at around 33 minutes.
