I'm surprised at all the negative response for what I consider one of the finest straight-ahead working groups in jazz today (granted, not a category with too many contenders, IMO). I think Extended Play is the best of the current band's output, and in a sense it makes the studio albums by this lineup relatively irrelevant, as most of the best compositions of the last several albums are included.
I do find the big band disappointing--basically the fluidity and tension of the small group are weighed down and subsumed by the charts.
Potter is fine, but Eubanks and Nelson are easily in the top ranks of their instruments.
