This is no sweeping-up of studio off-cuts. This is one of e.s.t.’s greatest albums, and even arguably their ultimate work, in every sense of the word. It represents a colossal achievement, as they take their final bow. The 2007 material might be extremely varied in tone and approach, partly out of necessity, doubtless governed by the available recordings, but this circumstance works to the album’s advantage. It’s a summation of where the trio had been, and also of where these perpetually evolving players were heading next.
