The estimable left-field hip-hop label Stones Throw’s latest podcast entry is a contribution by prolific producer Madlib. Recorded live at the Hella International event at last year’s Miami Winter Music Conference, it’s a short live set that emphasizes the rudiments — not just killswitch edits but simple, almost elemental musical elements, from a downtempo reggae snippet, to some mid-period John Lennon solo work, to rap instrumentals at their most automatic, all in a compact 20 minutes (MP3). At a time when so much rap music can sound like it was produced poolside on an diamond-encrusted laptop, this label is always ready with the muddy and sloppily soulful.
