Overall an uneven album, In Concert"s highest moments are sublime. The collection is culled from concerts with Big Brother and the Holding Company and Full Tilt Boogie. "All Is Loneliness," with Big Brother, was an improvisational vehicle for Joplin unlike any other, and no other performance of this tune, which conveys a terrifying loneliness, is even remotely similar. The version here was recorded at a 1970 reunion with Big Brother, and Joplin at one point--"There ain"t no TV, no radio, no nothin", man"--simply rips your heart out. We"re also treated to the impromptu 12-bar blues of "Ego Rock," wherein Nick Gravenites and Joplin toss blues lines back and forth in an affectionate but competitive repartee. Joplin was looped during the outdoor gigs with Full Tilt. A lot of tequila went down the hatch on the festival train that puffed its way across Canada in July of 1970. It was four months before Joplin died, and her Calgary performance of "Ball and Chain" is inspired, brilliant, drunk, uncanny, and frightening. It"s like work from the other side. --Myra Friedman
