Mr Alexander was selling band merchandise for Eagles of Death Metal, who were performing at the nightclub, when he was killed.
The concert - called Peaceful Noise -  marked the official launch of the Nick Alexander Memorial Trust, which will provide musical equipment to small charities and vulnerable groups across the country.
Mr Alexander's older sister Zoe, 43, said the event was "really personal" to Mr Alexander and included performances by artists who had toured with her brother or were friends with him.
She said she would remember her brother as someone who "approached life head on".
"He packed a lot into those 35 years so we will remember him in that way - as somebody who embraced life and forged their own path," she said.

Abubakar Bana, from Hornchurch, Essex, and Jordon Archambie, 20, of Stratford, east London, were convicted following a trial at the Old Bailey.
Daniel Welch, 34, of Winstead Gardens, Dagenham, and Zakar Yunas, 22, of Rokeby Steret, Stratford, were found guilty of violent disorder.
Mussa Jalo, 21, from Norfolk Road, Dagenham, had pleaded guilty to violent disorder at the start of the trial, along with Bana, of Station Lane, and Archambie, of Hesketh Road.
Jurors in the trial heard that Mr Ali was sat in his car along with two friends waiting for what they thought was a drugs deal.
A Mitsubishi Shogun 4x4 then rammed into Mr Ali's car, shunting it forward, while a red Renault Megane pulled up alongside and the occupants got out armed with weapons.
Mr Ali and two other men ran away but they were chased and the 33-year-old was stabbed to death in Braintree Road.
Det Ch Insp Dave Whellams called it a "pre-planned and orchestrated murder".
"Regardless of what Raja's intentions were that night, when he arranged to meet these men he should not have lost his life.
"I hope Raja's grieving family are able to move forward knowing his attackers have now been brought to justice."
All will be sentenced on 3 July.
