I absolutely loved Jakobsons' last solo album (Darwinsbitch's Ore), but her many collaborative releases since then have varied quite a bit in both style and quality.  Recently, however, she has been on a definite hot streak, as both Myrmyr's Fire Star and the Espvall/Jakobsons/Szelag album were pretty amazing.  Glass Canyon does not quite keep that impressive momentum going, but there are enough flashes of inspiration to make it an intermittently satisfying effort nonetheless.
