Beach Boys legend Brian Wilson has postponed his dozen-show spring run, citing mental health issues. Wilson, who has battled mental illness and depression for decades, was set to kick off a string of mostly East Coast dates tonight (June 7th) in Lynn, Massachusetts.

Wilson posted an open letter to fans on his social media platforms:

Dear friends,

It is with great regret that I need to postpone my upcoming June tour.

It is no secret that I have been living with mental illness for many decades. There were times when it was unbearable but with doctors and medications I have been able to live a wonderful, healthy and productive life with support from my family, friends and fans who have helped me through this journey.

As you may know in the last year or so I’ve had 3 surgeries on my back. The surgeries were successful and i’m physically stronger than i’ve been in a long time.

However, after my last surgery i started feeling strange and it’s been pretty scary for awhile. I was not feeling like myself. Mentally insecure is how I’d describe it. We're not sure what is causing it but i do know that it’s not good for me to be on the road right now so I’m heading back to Los Angeles.

I had every intention to do these shows and was excited to get back to performing. I've been in the studio recording and rehearsing with my band and have been feeling better. But then it crept back and I’ve been struggling with stuff in my head and saying things I don’t mean and I don’t know why. Its something i’ve never dealt with before and we cant quite figure it out just yet.

I’m going to rest, recover and work with my doctors on this.

I’m looking forward to my recovery and seeing everyone later in the year.

The music and my fans keep me going and I know this will be something I can AGAIN overcome.

Love & Mercy,
Brian Wilson

Brian Wilson's cousin and Beach Boys co-founder Mike Love posted a message on Facebook, which read:

Today, I read a message shared by my cousin Brian. My heart is swollen with love, compassion, concern, and thoughtful well wishes for a speedy recovery. Brian, you have fought bravely your battle with mental illness, I have no doubts that you will triumph and move gracefully past this speed bump. Let the music that lives deeply inside you carry you to your highest beautiful self, I will carry you in music every night we perform. I am cheering for you!

I Love You Cuz and I hope and pray to see you soon.

Peace & Love
Cousin Mike

In the 1995 documentary, I Just Wasn't Made For These Times, Brian Wilson recalled that around the time of the Beach Boys' 1966 Smile sessions, his mental illness and auditory hallucinations began in earnest, which eventually put a horrific strain on his personal and professional life: "I remember hearing voices in my head. Voices say, 'We're gonna kill you, you gonna be murdered, you have two years to live, we're gonna sabotage your music, we're gonna kill your wife, we're gonna shoot your daughters' -- very, very, evil. Very evil kind of thing. Evil trip."

In 1976, brother Dennis Wilson recalled the scene around Brian's metal and emotional decline during the latter half of the 1960's: "I would go to his house daily and beg, 'What can I do to help you?' Forget recording. Forget all of it. It got to Brian's health. And then, as the Beach Boys were slowly slipping away, y'know, we're at home trying to take care of our brother."

Brian Wilson with Al Jardine and Blondie Chaplin will next perform on August 9th in Waterloo, New York The Vine at del Lago Resort and Casino.

A joint tour with the Zombies is set for August and September
