The Robert Glasper Experiment is a quartet centered around jazz pianist Robert Glasper, and originally featuring bassist Derrick Hodge, drummer Chris Dave (from the pianist's acoustic trio), and Casey Benjamin on saxes and vocoder. They made their debut on one half of Glasper's two-disc Double Booked for Blue Note in 2009. While the first half featured Glasper's acoustic trio, the Experiment contrasted on the other, incorporating elements of neo-soul, hip-hop, and jazz-funk into its sound. The Robert Glasper Experiment is also open to working with vocalists. On its second CD -- and first stand-alone effort -- Black Radio, the group worked with everyone from vocalists Bilal, Ledisi, Erykah Badu, and Lalah Hathaway to rappers Mos Def, Lupe Fiasco, and Shafiq Husayn, to name a few. Black Radio was issued in February of 2012, also on Blue Note. In 2013, the Robert Glasper Experiment (now including Hodge and Benjamin with drummer Mark Colenburg) returned with their equally star-studded sophomore album, Black Radio 2. ~ Matt Collar & Thom Jurek, Rovi
