SAMPLE SLAYER—Good reasons to see DJ Shadow in concert right now, even though his best-known album came out in 1996: he's still mixing awesome, creepy, unique music; he has a habit of playing new work live; and his spooky beats make the perfect soundtrack for October's early nightfall and the creeping sense of Halloween.

ODD COUPLE—Although Isobel Campbell hanging out with Mark Lanegan gives us the same unsettled feeling we got when our pretty sister started dating the neighborhood dirtbag, there's no denying they make beautiful music together. His weathered rasp and her gentle murmur contrast perfectly, making for spooky country noir with a tinge of gothic romance. NL
