In the last decade or so, many metal musicians realized that while writing songs about demons and wizards was kind of cool, it was also a little silly. So they turned to largely instrumental music with titles that hinted at that world without the potential embarrassment of having to come up with a rhyme scheme for a term like "kwisatz haderach." Trees took that concept one step further on its debut release, When the Three Beggars Arrive (slated for release this Saturday, May 7, at 3 Kings Tavern), naming the music with section titles like "Part One" and so forth. And that's just as well, because the band's colossal yet dynamic songwriting goes beyond being merely bombastic and loud in its delivery; it's also able to convey a sense of story and movement. Live, Trees provides a dense, crushing interpretation of its recorded epics.
