true.

audio from the show + ^Truck North^s comments, looks like Hub is gone
this is sad to hear and he will truly be missed.
good luck Hub and enjoy your time off (in case you make a return).
i think a Leonard Hubbard appreciation post is in order...

lol, even Wikipedia is up on this shit:
"According to the Root's website, Hub (bass), has been rumored to have parted ways with the group."
