"To me it already feels like it's right up there, mainly because from day one it was based around music, live music, including design aspects like acoustically treated wave walls to diffuse sound or a concrete stage and flooring that helps diminish low end feedback.
"We paid attention to those little details right from the start and then there's the structure of the building itself and its size. This boutique way, it's the winner," he said.
"Our kaupapa at King Street Live has always been that we wanted to set up a good venue for good people to have a good time.
"We had a major promotion company come and look at us just the other day and they're wanting to be the next to book, so everything feels really good - you set up with the right expectations and objectives, word gets out, and you're on to a great thing."
Maxwell, who also owns Stone Feather studios in Featherston, had been working on numerous other musical projects as well but said TrinityRoots had "never been far from me" since first forming during the 1990s when sonic paradigms were shifting.
The group disbanded in 2005 and reformed in 2010 but had not performed together since the Natural Festival in Perth last year.
He was eager to take the collection of new tunes for a burst around the block alongside bassist Rio Hemopo and new drummer Ben Wood, he said.
"Trinity came out of a time when people were breaking down boundaries and mashing up a whole lot of ideas.
"There was no fear and you got together and tried experimental fusions of different styles of music.
"We're still like that but the palette is fuller and there's more colours. This is like the phoenix rising out of the ashes and it feels energised and alive," he said.
"The new songs reflect our individual growth and our maturity and observations of what we're going through as parents, community members and partners."
Maxwell said the establishment of the new venue, which had enchanted artists and industry players throughout the country and internationally, had been instrumental to TrinityRoots hitting the road again.
"King Street has been a big part of the impetus to really get Trinity cranking and get our touring career back on track.
"People from all the over the world have been asking, you know, come to Brisbane, come to Poland, come to Portugal. King Street lit the fire for that phoenix, definitely."
TrinityRoots plays King Street Live on Thursday night.
