When does something shift from a trend to a movement? Since OneFour burst on the scene with "The Message", the aggressive Australian drill subgenre has rapidly gained momentum, spreading through the outer suburbs of Sydney and Melbourne like a ching-waving contagion.

After West Sydney and the outer South-Eastern suburbs of Melbourne claimed their place on the map, it was only natural that Melbourne's west would be next up. St Albans duo 30Kingz — a reference to the area's '30' postcode prefix — add their chapter to the Australian drill story with "Business Men". The verses, from Levz and Sweetz, meet somewhere between menacing and motivational, while the beat from Levz elevates this one to instant anthem status.

Visually, this one is a ride through St Albans, as the deep crew push big-body utes and SUVs through the suburb's main strip. Appropriate to their location, St Albans streetwear label Saint Side is the uniform.
