Chamberlain, whose projects include Machete Clan and Something Zesty, said that the band had been able to grow a "pretty loyal fanbase" in the last couple of years, and he was happy to be able to offer them a brand new track.
"We've only got five songs out at the moment, so it was important for us to release some new content and put a bit more 'bait on the hook'".
"Having Liam Robertson playing bass now has meant that he's brought a whole bunch of new ideas in as well, and he pretty much drives this new song.
"It's definitely a step up for all of us, in terms of ambition as well."
Chamberlain said he had completed the animated music video for 'The Machine' during lockdown, which he had initially thought would have been "impossible" until Covid-19 had provided him with "weeks and weeks" of downtime.
"It's quite 'staggery' animation, which saved me some time.
"The message of the song itself is quite impactful too I think, especially with the video, and it focuses on the capitalistic times we're living in.
"It still feels really Drxnsey though, and I think it's a good step forward for the band.
The new single was the first to be recorded without a metronome, Chamberlain said, after drummer Ethan Coleman had laid down a guide track that was "too good not to keep".
"That definitely gives the song a much more human feel, and there are parts that speed up a tiny bit and then pulls back.
"It does feel like it's breathing a bit and definitely adds to the intensity of the parts."
