Brian's older brother, Jason, and their parents are employed at casinos in Atlantic City .^{[citation needed]}

While attending Holy Spirit High School , a friend signed him up for an audition with Brothers Entertainment without Joo's acknowledgement. The company has discovered several Korean-Americans who wish to pursue an entertainment career in South Korea. After several months of training, he was sent to SM Entertainment in South Korea, and on December 9, 1999, made his debut as one of the two members of Fly to the Sky , along with Hwanhee , at the age of 17.

Joo has appeared on television many times. Since 2005, he has appeared on a number of variety shows , including hosting MBC'sMusic Corein 2006 and becoming a host for SBS 'sGreen Goldin 2009.

In August 2009, Fly to the Sky decided to work on separate projects and have become solo singers under different labels.

Originally scheduled for released in November 2006, the album was postponed to December. The album incorporated diverse genres such as classic pop , soul , and jazz . With this album, Joo hoped to gain more respect as an artist, rather than being known as "Fly to the Sky without Fany".He describes the reason for the solo album as,

First of all, I just wanted to do it. I also wanted to show that I could [be successful] as Brian( sic ). When (Fly to the Sky) sang, many think Fany is the main vocal, and that I am the second vocal and a rapper. I won't mention his name, but one producer once said to Fany, "You are a really good singer", when he only said "Good job", to me. So I wanted to prove that I could do it too.

On January 21, "가지마" (Don't Go) was selected as the "Mutizen Song" on SBS Inkigayo .Due to hectic schedule, Joo has been suffering from vocal fold nodule .

Brian is interested in breaking into the American music industry, as Rain and Se7en are doing, but is waiting for the right opportunity.

Most recently, Joo starred (as himself) in the English segment of the mini-series, Homey Korean, presented by Arirang. Joo - along with co-star and real life friend, Chris Pemberton - teach basic Korean language as well as discuss the culture, landmarks, popular tourist sites, and daily life of Korea to English-speaking foreigners.

Recently, Joo made a cover version of Jason Derülo 's " In My Head ".

7 April, Joo released his new mini album UNVEILED.

May 2011, Joo released the mini album UNVEILED trough iTunes. He tweeted:“Great news~! My Mini-Album “UNVEILED” will be released on iTunes on May 17, 2011~ Spread the word & let’s get me up on the iTunes charts ;)”

The title song wasLoved, It's Now Over. A representative from Jellyfish Entertainment stated: “Brian is recognized as the person who’s always making people laugh, but he wanted to show that he does have other feelings such as sadness and pain. I think you’ll be able to see a more diverse side of Brian through the album that will be released soon and the music video.”

On March 21st, 2012, Brian Joo performed at 2K12 Korea Night: Seoulsonic at Kool Haus in Toronto along with artists such as A Pink , Teen Top , G.NA and many more. The show was hosted to around 700-1,600 fans and it was also stated that some fans couldn't get into the concert (even with tickets) because the venue was filled. Brian Joo stated in an interview that he loved Toronto very much, was surprised by how kind and calm the fans were, and stated that once he retires he would like to come and live in Toronto permanently.
