For its fifth album, the Brazilian prog band Dialeto collaborate with King Crimson’s David Cross. The result is outstanding in its field, starting with eight short pieces by Béla Bartók that retain their haunting folkloric origins even as they are transliterated into another genre entirely. Their Eastern European harmonies and rhythms are amped up into convincing heavy rock. The remaining tracks come from the Crimson and Cross catalogues and are rendered movingly with no injustice to the original recordings.
