Reminiscent of PJ Harvey, experimental noise rocker Lauren Kathryn Newman - aka LKN - is a one-woman dynamo whose music is energetic, intense, and aggressive. The multi-instrumentalist records solo - playing all instruments and writing all songs - but gathers up a makeshift band for her explosive live gigs. The Portland-based musician first grabbed the spotlight when she formed the Florida punk band Stellamarie in the summer of 1999 with longtime friend and bassist Sarah Highnote. A combination of LKN's first four-track solo outing, You and No One Else, and the band's self-titled debut in 2001 leads her to play several festivals, including SXSW.  LKN's sophomore release, 2004's In the Leap Year, was another gritty example of her raw energy as she raced through three high octane instrumentals with a feedback focus.  Television's Richard Lloyd lent a fiery guitar solo to the bluesy track "To Bring You My Love."  When Newman isn't recording or performing, she pounds the skins for several bands including, Portland's Avenue of the Strongest, Boston's Yellow Fever Sweethearts, and Pensacola, Florida's GGJOE.  Stellamarie released its second disc, 10 Songs, earlier this year to stellar reviews across the board, and Newman's new record, titled Postulate, is due out April 11.  Saturday, April 8, 9 p.m., Le Voyeur, 404 Fourth Ave. E., Olympia. - Tony Engelhart
