The Silver Boulders were a band formed by Nat and Alex Wolff, along with their friends Thomas, David and Josh.
Main article: The Naked Brothers Band
Nat and Alex started off as a duo called The Naked Brothers Band, which also included their friend Cole Hawkins. After he moved to Connecticut, they changed the name of the band to The Silver Boulders in order to "give the band a more classier image". Nat invited his preschool friends Thomas, David and Josh to join them, due to having their own drums, keyboard and guitar, respectively (though Thomas couldn't play drums well and loaned them to Alex, choosing to play cello instead; Josh got a new guitar for Christmas and chose to play that).
Cooper Pillot, another friend of Nat and Alex, became the manager of The Silver Boulders.
