The album was released in mid 1984 on MCA in the United States and the United Kingdom, two years after Frey's modestly successful debut album, "No Fun Aloud" and four years after the demise of the Eagles.

He began his solo career with "Pictures at Eleven" in 1982, followed by 1983's "The Principle of Moments".  Popular tracks from this period include "Big Log" (a Top 20 hit in 1983), "In the Mood" (1984), "Little by Little" (from 1985's "Shaken 'n' Stirred"), "Tall Cool One" (a #25 hit off 1988's "Now and Zen"), "Manic Nirvana"'s "Hurting Kind (I've Got My Eyes on You)" (1990), and "I Believe" (from 1993's "Fate of Nations"), another song written for and dedicated to his late son, Karac.  In 1984, Plant formed a short-lived all-star group with Jimmy Page and Jeff Beck called the Honeydrippers, who had a #3 hit with a remake of the Phil Phillips' tune, "Sea of Love" and a follow-up hit with a cover of Roy Brown's "Rockin' at Midnight."  Although Plant avoided performing Led Zeppelin songs through much of this period, his tours in 1983 (with drummer Phil Collins) and 1985 were very successful, often performing to sold-out arena-sized venues.

Guess Who (rapper): Laurenţiu Mocanu (born June 2, 1986), better known by his stage name Guess Who is a Romanian rapper.  He began his career as a member of the rap group Anonim along with group members Zekko and Griffo, and later launched a successful solo career in music.  He is one of the most successful artists from the new wave of Romanian hip hop and has gained considerable appreciation and mainstream attention in his native Romania following the release of his first solo album in 2009 called Probe Audio (Sound Check).  Guess Who gained popularity as a solo artist in 2007 when he leaked three tracks he had recorded for his solo album on the Internet.  The feedback was overwhelmingly positive and his cynical and ironic approach to writing quickly earned him a large fanbase.  Even though he repeatedly delayed for over two years releasing his first album, the Romanian audience received it well and he even gained attention from high level Romanian music executives when his video for the first single Tu (You) was aired on the Romanian music channel 1Music.

Peter Kingsbery: Peter Kingsbery is an American singer songwriter who cofounded the band Cock Robin in the 1980s.  He grew up in Austin (Texas) where he studied classical music.  He moved to Nashville (Tennessee) where he began his career as a musician (he accompanied Brenda Lee on piano on a few tours) and then to Los Angeles at the end of the '70s where he began a career as a singer/songwriter.  He composed a few songs for Smokey Robinson, and one of his compositions, "Pilot Error", sung by Stephanie Mills, got some success in the dance charts in 1983.  At the beginning of the '80s, he founded the group Cock Robin with Anna LaCazio, Clive Wright and Lou Molino III which enjoyed great success in Western Europe mainly.

After the band split up in the early 1990s after a third album, Peter Kingsbery enjoyed a fairly successful solo career, releasing four albums over a decade, and scoring a major hit in France with the song "Only the Very Best."  With his fourth album he tried his luck singing in French, the language of his adopted country (living there since some years back).

The Itals: The Itals are a Jamaican reggae vocal group formed in 1976 by Alvin "Keith" Porter, Lloyd Ricketts, and Ronnie Davis (currently a member of The Tennors), all of whom had previously also recorded as solo artists.  All three had worked together in the late 1960s in The Westmorelites.  The group recorded several albums through the late 1970s and 1980s, with Ronnie Davis going on to a successful solo career in 1997 as Ronnie Davis and Idren.  The Itals' debut single, "In A Dis Ya Time", is regarded as the group's finest work, and topped the Jamaican chart.  1987's "Rasta Philosophy" was nominated for a Grammy Award as Best Reggae Album.  The line-up has changed over the years, with former solo artist David Isaacs joining in 1987 when Ricketts was sentenced to a prison term, preventing him from travelling to the United States.  Davis left the group in 1994, and was replaced by Porter's daughter Kada.  The Itals continued to tour in 2009 in support of the newly released "Let Them Talk".  In 2011 original member Lloyd Ricketts was able to obtain a work permit and performed two shows with Keith and Ronnie before his death.  Ronnie Davis stepped away from The Itals again in 2012 and reunited with the Rocksteady group The Tennors, but Keith continues to tour with two of his children, Darien Porter and Kada Porter, providing harmonies.  Keith will be releasing "Mind Over Matter", the remastered compilation of 22 early Itals songs and a solo album of reggae covers of classic R&B songs, called "Let's Get it On" in July 2015.
