Friends of the Brooklyn rock group the Yellow Dogs held a benefit and memorial service Monday for the musicians who were slain in Williamsburg.

Hundreds gathered at Brooklyn Bowl to pay tribute to brothers and bandmates Soroush and Arash Farazmand, who were killed last week by a disgruntled fellow Iranian musician.

“They were great guys, and we will miss them,” said friend Mustapha Abdou, 26. “It’s shocking. They were very talented.”

Also killed was a friend, artist Ali Eskandarian.

Musicians such as Nada Surf, TV on the Radio, and James Chance performed at the event in Williamsburg.

Crazed gunman Ali Akbar Mohammadi Rafie killed himself after the triple murder on Nov. 10.
