Here we have another excellent chapter in the "Constant" series. "Constant" pieces are works of minimal drone that tend to use a "less is more" approach. The idea of these songs is to create the least possible ambient drone material necessary for listening. Mystified created the first "Constant" on Webbed Hand Records ( www.webbedhandrecords.com ). Several artists gave the theme their own spin at the TZP Drone Company ( http://www.archive.org/details/tzpdc ). Treetrunk Records has now begun exploring the "Constant" theme. "Constant 11", by Mystahr, is a longform work, completely improvised, that gives a distinct sound quite a bit of variety while remaining consistent. "Constant 12", by Jon 7 is a textured minimal drone full of mystery and interesting layers.
