With three big bands across four days, The Street Machine Summernats is set to draw a big crowd.

Friday night's entertainment kicks off with punk/hip-hop band 28 Days.

The five-piece first introduced their trademark sound to the scene 20 years ago, and are best known for hits including 'Rip it Up', 'What's the Deal?' and 'Sucker'.

"We're definitely looking forward to a big hit out at Summernats. It's a crazy crowd and that's exactly what we like."

Coming off a massive national tour to launch their fourth album and #2 ARIA debut, Everyone We Know, Aussie hip-hop giants Thundamentals are headlining Friday night at the Nats.

"Thundas are pumped about hitting the Summernats. We hear the Nats gets pretty wild on Friday night, and it's gonna be a heap of fun with the guys from 28 Days there too."

Saturday night sees multi-platinum selling rockers Wolfmother returning to Aussie shores to headline the festival.

With a massive global following playing to sold out crowds around the world, as well as sharing the stage with rock royalty including Guns N Roses, Aerosmith and AC/DC and many others, Wolfmother have spent most of the last 18 months touring the world promoting their latest album, 'Victorious'. With a Grammy alongside ARIA, APRA and other awards, Wolfmother's dynamite live show will tear up the Summernats main stage.

The festival attracts more than 100,000 people from Australia and around the world, where modified car enthusiasts and music fans get together and party with a massive display of world-class show cars, the tyre-frying madness of the Burnout Masters, live concerts and the crowning of the Summernats Grand Champion after four unforgettable days of motoring and music mayhem.
