Jazz fans should make a point to take a trip to Galesburg this weekend for the second annual memorial concert for the late jazz and R&B guitarist and singer Ken Henderson - who spent most of his life around Galesburg raising a family on a farm.

• The audio alchemists of Negativland have done it again, challenging listeners with an electronic cacophony to accompany their latest "art damage" project, entitled Death Sentences of the Polished & Structurally Weak.

This Tuesday brings an avalanche of soundtrack CDs from upcoming films and music-fueled television dramas. Epic Records' release of the Moonlight Mile soundtrack is a well-conceived quilt of iconic hits and interesting choices.

The raking guitar and pounding double bass drums might hurt your mom’s ears, but when the lyrical content contains everything from Jungian and Melchezekian philosophy to a disturbing sexual metaphor for social numbness, it’s worth a listen.

• Taking Pearl Jam's idea and turning up the speed, The Who has announced that it will soon be issuing a series of CDs that documents each concert from the band's 2002 North American tour. Each two-CD set will bear the Encore series brand and is being made available by Eel Pie Records and TheMusic.
