Barquin D'an is a Bith musician from the planet Clak'dor VII who plays a Kloo horn, a fictitious wind instrument that resembles a bassoon. He is the estranged older brother of Figrin D'an, and resents the success of his brother's band, the Modal Nodes. He travels to Tatooine to join the Nodes, who are nowhere to be found after his arrival. Barquin stays to perform with local musicians and eventually joins the Max Rebo Band; unaccustomed to the depravity he witnesses in Jabba's Palace, he flees after Oola's gruesome death. After Jabba's demise, he quits music altogether and starts an import/export business.
