Bands, labels and festivals have backed a near-silent ad campaign that warns the NSW government's safety-focused licensing regime could crush the music industry.

The Australian Festivals Association on Tuesday urged voters across NSW to ask their local candidates "whether they support live music when deciding who to vote for" in the March 23 state election.

NSW this year began forcing some major festivals to meet stringent health and safety regulations after five drug-related deaths in as many months.

Read Next Falls Festival said the government had "made it clear through new unnecessary regulations" they wouldn't work with the music industry.

"Turn up live music. Turn down the current NSW government," it said in a post highlighting the campaign.

The video ad shows performers and attendees at music festivals depicted as TV static silhouettes. White noise plays in the background.

Industry group ARIA backed the campaign while bands The Rubens, Sheppard and country musician Casey Barnes changed their social media profile pictures to ones of TV static.

The regulations force 14 "high-risk" festivals - including Laneway and Defqon.1 - to prove to the Independent Liquor and Gaming Authority they've met stringent health and safety measures.

The new measures predominantly target festivals involving young people, crowds of more than 8000, electronic dance music and events where a recent serious drug-related illness or death has occurred.

Five people died at NSW music festivals in the five months to mid-January 2019.

Paul Toole, the minister responsible for the ILGA, has been contacted for comment.

He said in February that the NSW government "wants music festivals to thrive - but serious drug-related illnesses and deaths have demonstrated that we need to help make a small number of them safer".

AFA spokeswoman Adelle Robinson said the campaign aimed to make festivals an election issue.

"The festival regulations were rushed and the industry was poorly consulted and vastly underestimated," she told AAP in a statement.

"Importantly we want to ensure that voters understand they will need to preference every box to ensure their vote counts the way they want it to count."

Labor has pledged, if elected, to scrap the regulations and consult the industry about licensing.

"Labor supports the #votemusic campaign," music spokesman John Graham said in a statement.

"To save music in NSW we need to change the government."

Red Hot Chili Peppers bassist Flea condemned the new regulations as "the stupidest f***ing thing" he'd ever heard during a show in Victoria on March 2.
