NPR Filler Music

Where do these interludes
interspersed between such intellectual intercourse
come from?

Not the actual album songs they play
for some meaningful or ironic connection to a story;
I mean the random, untitled stuff.

Is there an official NPR music man
(mute - I imagine him,
letting everything out he can't say
in his music)
who conceives of all these artisanal arrangements
and then layers recordings of himself 
in his one-man-band studio?


Or is there an eponymous NPR band
of taciturn proto-über hipsters,
vowing silence for the art's sake,
with idiosyncratic clothing 
and 
carefully cultivated coiffures
typifying their auditory taste
for eclectic mixes of styles and instrumentation?

Can you imagine him
or them
going on tour:


the concert posters,
the confused yet enthused radio personality promoters,
the attendees?

The posh pits.
