On Monday night I went to Long Island to check out an unlikely a cappella enclave at (it's a mouthful) Plainview-Old Bethpage JFK High School. In short: Since 2001, six a cappella groups have popped up at POB/JFK. These are student-run a cappella groups that rehearse on Sundays, often arrange their own music, and operate in largely the same manner as their collegiate brethren. Which is to say they sing Guster tunes and have pun-y names!
Here's a look at the high school's mixed group, the very impressive Chock Full of Notes, singing Guster's "Demons." (Fun fact: As an undergraduate at Tufts, Adam Gardner of Guster sang with the Beelzebubs. More on that in Pitch Perfect, out on May 29th.)
And here is a look at the all-male B Sharps.
