"We have a real diversity of sound. We've got the electronica, we've got lots of jazz and free jazz, we've got hip-hop, we've got the sensibility of old soul and rock. There's lots of different tones and textures."
Stewart said the band's sound is influenced by the neo-soul (a style intertwining R&B;, hip-hop and soul) artists of the late 1990s, such as Lauryn Hill, D'Angelo and Erykah Badu, and the abrasive electronica of LA producer Flying Lotus.
For Stewart, who has been in the band since 2009, Brockaflowersaurus-Rex is unique not solely because of its sound, but the scale on which it makes music.
"Electronic music on the whole is moving towards a smaller scale," he said.
"For instance, it can be just a producer and their laptop. But we're the complete opposite.
"I've got a huge mixing desk on the stage. There's all the horns, there's the different sound effects. Plus, there's nine of us.
"We're not small and simple, we're big and difficult."
Also unique is the flavour added by rapper and tenor sax player Blair Clarke, who also plays the Maori flute and the porutu, another traditional Maori instrument.
"And he throat sings," said Stewart. "It adds a nice texture."
Brockaflowersaurus-Rex has played several types of gigs, from sell-out shows at Wellington's Bar Bodega and Rakinos in Auckland, to outdoor gatherings such as the Tora Festival (in South Wairarapa) and the Newtown Festival. "We've loved them all," said Stewart.
"Even if there's no one else at the venue, it's still a party, because there's so many of us."
After their show at King Street Live, Brockaflowersaurus-Rex will be embarking on a North Island tour, and will be releasing its debut album at the end of the year.
Brockaflowersaurus-Rex will be playing at King Street Live on Saturday July 20. Tickets are available from www.dash tickets.co.nz, at an early bird price of $10.
