Stockholm’s reformed death-metallers delve even further here into the pastoral forest of florid folk-prog. In love with nature and the occult — titles include “The Wilde Flowers,” “Will of the Wisp” and “Chrysalis” — they stretch one song past eight minutes, another past seven, another past six, and five more past five. The first two tracks each make a slight return later on, and “Sorceress” and “Era” swing their stuttering time changes like King Crimson or Jethro Tull on a funk bender. “The Seventh Sojourn” is a Mediterranean-flavored instrumental; “Strange Brew” has a Kraut rock-ish midsection. And much of the rest is just plain gorgeous.
