Close the week with one of the web’s most generous podcasts (MP3), the occasional hour-long sequences of music from artists and labels associated with brainwashed.com. The latest, dated July 16, features music by Out Hud, Mimir, Eau Claire, !!!, Kid 606, Richard H. Kirk, Electric Company, Barbez and Henry Jacobs. … And why not load up with two podcasts? A more recent favorite is the series from fatbeats.com, an online purveyor of vinyl and CDs. All hip-hop, but there’s always a handful of instrumentals tossed in; last week’s (episode five) included pieces by East Flatbush Project and Waajeed. The latest, episode six (MP3), includes instrumentals by Prozack Turner (remixed by Madlib), Evidence and Mass Influence.
