â€œI know we've always crossed between underground and pop sort of stuff, but I think mainly we've been more underground than we have over, if you can say that,â€ he reflects from London.
Nevertheless, the success of 'Push Up' - which reached number two on the national charts back in 2004 - and other singles like 'Get A Life' and the earlier 'B-Boy Stance' have seen Harvey and fellow founding member Matt Cantor tour the world as champions of breakbeat and party-starting electronica.
Since forming 15 years ago, the duo has released four studio albums - including 2006's 'Adventures In Freestyle' - half a dozen mix compilations and dozens of singles, all of which have struck a particular chord in Australia, a region where the duo remain hugely popular. As Harvey explains, however, their forthcoming summer tour promises a few surprises.
â€œWhat we've been doing for the past year or so is perfecting this 'decks and effects' [show] where Matt will be spinning the tunes and I'll be doing sound effects and scratching, accapellas,â€ he says.
â€œPeople will be hearing older tracks but in a newer way because they've got new things going over the top. We're also trying out a whole visual thing; we've had a visual reel done for us so we've upped the ante. It's the first one we've had done so we'll see how we go.â€
Having been firmly ensconced in the breakbeat camp for so long, Harvey is happy to reveal the Freestylers' new material - including recent single 'Cracks' featuring Belle Humble - demonstrates an evolving versatility in the studio. Dubstep is just one of many new influences present in their new music and their fifth album - slated for release some time in 2011 - aims both to connect with older fans as well as attract a new legion of Freestylers adicts.
â€œWe've been coming there (Australia) since about '98; obviously the crowd has changed,â€ he says. â€œA lot of people are maybe just getting into us so it's kind of good that we're attracting new fans as well.â€
