You might sizzle in the hot sun and be swamped in a crowd crush but your ears will thank you.

The heat is on and so are the annual Australian summer music festivals, promising sweet music from some of the world’s biggest names.

One of the blockbuster events, the Big Day Out, will kick off from January 19 on the Gold Coast for those who fancy hot, long Aussie days with a sprinkling of good rocking.

Headline acts this year include rockers Pearl Jam and smooth-talking rapper Snoop Dogg, AKA Snoop Lion.

The festival then makes its way to Melbourne, Sydney, Adelaide and Perth.

Another iconic event, Falls Festival, kicks off on Saturday in Lorne, Victoria, on Sunday in Marion Bay, Tasmania, and on Tuesday in Byron Bay, NSW.

American alternative rock band the Violent Femmes will be joined by singer, songwriter and Beyonce’s cool little sister Solange, Crowded House frontman Neil Finn and local outfit the Cat Empire, who will all grace the stage.

For those who crave something more mellow, Queensland’s Woodford Folk Festival began on Friday and runs until New Year’s Day.

Now in its 28th year, the event bills itself as one of the world’s largest folk festivals and more than 500 acts will perform.

Folk fans can ring in the new year with a line-up that includes UK singer-songwriter Beth Orton and Melbourne songstress Clare Bowditch.

Three-piece band the Basics, featuring Wally De Backer, who most probably know better as Gotye, will also perform.

For those seeking something with more grunt, Soundwave heads to town soon.

The festival begins in Brisbane on February 22 before touring to Sydney, Melbourne, Adelaide and Perth with heavier acts including Green Day, Stone Temple Pilots, Alice in Chains, Megadeth, Placebo and Korn.

For those a little bit more country, the famous Tamworth Country Music Festival gets under way on January 17.

Meanwhile, blues fans can get their fix at the Thredbo Blues Festival, now in its 20th year, which kicks off the same day featuring Wendy Matthews, Jeff Lang and Rick Price.
