When one writes about Brian Wilson, the legendary leader of The Beach Boys and one of the most celebrated musicians of all-time, it is hard to avoid clichés.

Often touted as a genius, Wilson's name is frequently listed alongside the likes of Bach and Mozart rather than other pop musicians. His name has become shorthand for the perfectionist pop auteur. And he is responsible for creating some of the most beloved songs of the last 60 years.

But actually speaking with the man reveals a humble soul, one who is simply honoured that he has been able to maintain a career making people smile with his music.

"It is a great honour and privilege to have people like us," Wilson says. He takes particular pride in the continued popularity of The Beach Boys among young people. "Young people these days still like The Beach Boys and can like their own stuff. It's nice we can be side-by-side." 

Wilson's humility, however, does not convey just how jam-packed the last three years of his life have been. In fact, his schedule has been busier than almost any other stretch in his illustrious career.

Since 2014, Wilson has had a movie made about his life, published a memoir, released an album and performed over 150 tour dates around the world in support of Pet Sounds' 50th anniversary.

That tour, which began in late March 2016, has taken Wilson and his band to four continents and more than 20 countries, for a total of 185 shows. When I point out that musicians who are in their 20s can get overwhelmed with only a few weeks worth of dates, let alone nearly two full years around the world, Wilson seems to shrug it off.

"It is rejuvenating," he says. "Very much so."

The tour was created ostensibly as a farewell to The Beach Boys' seminal album Pet Sounds, offering fans a last chance to hear Wilson perform the beloved LP live. Wilson, himself, understands the connection.

"I'm kinda sentimental to Pet Sounds," he explains in his characteristically humble and understated manner. "But it's in the final stretch."

But beyond playing all 13 tracks from that celebrated record, Wilson has enjoyed the opportunity to trot out more than two dozen of his most cherished songs. He is adamant that every song he would ever want to play for audiences is on the setlist.

When I ask Wilson if there was any difficulty in picking some of these songs back up 50 years after their creation, he quickly puts the idea to rest.

"No, no, no, it's not hard at all! We've been practicing for years," he says with a chuckle. "So we know the songs pretty well."

Wilson adds that "it's fantastic" to have seen so many fans out to the shows to sing-along with his songs, as he has played to sold out audiences all over the world over the last year-and-a-half.

Getting the chance to revisit so much of the world has been its own little joy for Wilson, but two places in particular were particularly special for him.

"I've always liked Australia and Japan," he says. "I don't know, they just have always liked our music!"

After the Pet Sounds tour ends in October, Wilson has only one plan: "I'll be doing a rock n' roll album!"

While he admits that he hasn't written any songs just yet, Wilson says that he envisions the album will have some originals, as well as "covers of great artists like Chuck Berry, Bill Haley and Little Richard."

Wilson adds that the death of Chuck Berry, the rock n' roll icon whose riffs were integral to the early days of The Beach Boys, was particularly tragic but that he hopes to serve his legacy well with this new record.

"It saddened me to see him die," says Wilson, "but he did teach me a lot of rock n' roll melodies."

In preparation for the record, Wilson says that he has been listening to a 1960s music channel to help him cultivate some of the vintage rock n' roll sound he hopes to achieve with this new album.

Given Wilson's busy schedule, as well as his much publicized personal difficulties over the years, it is something of a marvel that he continues to be as creative and energetic as he is. But Wilson matter-of-factly credits his longevity to three things: "I get a good sleep at night, I eat healthy food and I exercise."

Wilson says that his walks are one of his favourite parts of his day, and they are key to keeping his mental and physical well-being up. "I walk. I walk by myself," he explains. "It helps me get away, clear out my brain and get my leg muscles working good." 

But for more difficult days, days when he is feeling down or a little sapped of energy, Wilson has a different solution.

"I turn to music," he says. "My music can be very therapeutic. It feels good to play the piano." Wilson says that he plays the piano about once a week when he's off the road.

But Wilson still has tour dates booked through the middle of October and finding time for relaxation and self-healing can be a little trickier. While on the road, Wilson and his bandmates rely on each other to keep their spirits and energy high.

"When we take time off, we get to rest," he explains. "But when we go on the road, we are doing concerts almost every night. So we do a thing called 'circle up' where we talk to each other and prepare each other for the concert.

"We all have our input," Wilson continues. "There are 12 of us and each guy has a little bit to say. I usually just say, 'Let's knock 'em dead tonight!'"

And knock 'em dead they do. Wilson and his band -- which includes longtime Beach Boy stalwarts Blondie Chaplin and Al Jardine, as well as Jardine's son Matt -- have led the world in one last celebration for arguably the most celebrated album of all-time.

For Wilson, who famously toiled over every last detail of Pet Sounds and struggled with the album's initial criticism, it is a previously unimaginable end to a decades-long journey.

"I never could have imagined," he says. "I never could have. It's fantastic."
