Truth be told, the

Sonic Youth
. They may have been at the peak of their popularity, but they had traded their experimentalism for sheer, bracing noise. It may have sounded good, but ultimately
Dirty
didn't have the cerebral impact of
Sister
, largely because it was tied to an admittedly effective backbeat. Beginning with
Washing Machine
,
returned to more adventurous territory, and in 1997, they released a series of EPs that illustrated their bond with such
post-rock
groups as
Tortoise
and
Gastr del Sol
. Those EPs, as well as the epic
closer,
"The Diamond Sea,"
provide the foundation for
A Thousand Leaves
, the band's most challenging and satisfying record in years. The blasts of dissonance that characterized their

, and
Kim Gordon
, which keeps the lengthy songs captivating. Both

Gordon
's noisy politicized rants sound a little out of place, but her best moments (
"French Tickler,"
"Heather Angel"
) have unsettling, unpredictable twists and turns that greatly contribute to the success of
