Input: What came next was an unbilled guest: Bilal  the shape-shifting R&B vocalist who has known Glasper since the first day of freshman year at the New School for Jazz & Contemporary Music in New York. They dug into "All Matter " a tune that first appeared on Glasper's 2009 album Double Booked  later resurfacing on  Bilal 's 2010 release Airtight Revenge. The lyrics establish a philosophical reflection well suited to our times:
Glasper and  Bilal  have performed "All Matter" countless times  always managing to find some new motivation in the song. This performance features a keyboard solo that starts out terse and gradually opens up and expands  hinting at some tricky rhythmic displacement that Tyson later ratifies  in his spectacular drum solo.
