Proceeds from ticket sales, livestreams and donations will go towards supporting the partner music venues while they remain closed.
The venues joined forces to programme the gigs to help support and protect the city's vibrant music scene as the coronavirus restrictions continue.
Live Is Alive! took place as socially distanced events at Brighton Dome and via livestream over three consecutive Saturday evenings.
The final gig, which was due to take place on 7th November had to be postponed due to the latest lockdown restrictions and is set to be rescheduled in the new year.
Each event featured four local bands - from the ambient electronic sounds of duo Immersion to the high-energy punk spirit of Wife Swap USA - performed to a live audience of two-hundred-and-fifty in Brighton Dome's Concert Hall.
The gigs were the first live events to take place in the venue since closing in March and featured enhanced safety measures to allow the socially distanced audience to attend.
The Live Is Alive! collective of partners said:
"Live Is Alive! has been overwhelmingly positive in reconnecting artists, venue staff and audiences back in a venue to do what we do best.
"Thanks to Brighton Dome for staging the gigs and to all the music fans for raising much-needed funds for our live music venues.
"We look forward to the final night being rescheduled soon and we will continue to campaign to save our venues so we can bring live music back to the city."
Brighton & Hove's live music scene is one of the city"s great success stories, generating an estimated £112m per year for the local economy and plays a key role in its position as a creative, cultural and tourist destination.
Since social distancing and lockdown measures were implemented, most of the grassroots music venues have been unable to re-open for performances and are facing a financial crisis that could lead to permanent closure.
