If Gang of Four has provided the spastic, trebly reference point of most recent disco punk, Konk surely has contributed to the solid rhythmic backbone of the genre. Their influence on !!! is unquestionable, at least. Relishing in the melting pot of late-1970s New York, the band fused their post-punk approach with skewed but learned takes on soca, Latin jazz, salsa and nascent hip-hop to create a racially ambiguous but undeniably upbeat dance sound. And though Soul Jazz has left off a few of Konk’s most uncommon pleasures, this is a welcome introduction.
