input: Kennedy has become very well known for his collaborations with Guns N' Roses lead guitarist Slash. In late 2009, it was reported that they would be working together on Slash's self-titled debut solo album. Slash later confirmed that Kennedy was chosen to sing and co-write the final song, "Starlight", on his album. Other musicians who appeared on the album include Ozzy Osbourne, Adam Levine of Maroon 5, Dave Grohl of the Foo Fighters, Kid Rock, and Chris Cornell of Soundgarden. Then, according to MusicRadar, Slash asked Kennedy to co-write and sing another song, "Back from Cali", which was added to the album at the last minute, making him the only musician to appear on more than one song on the album's standard track listing. The album was released in April 2010. On February 3, 2010, Slash announced that Kennedy would be the lead vocalist for his band on tour. On tour, Kennedy performed a number of songs found throughout Slash's catalog. Slash and Kennedy were also the supporting act on Ozzy Osbourne's tour in 2010. The other members of Slash's band are rhythm guitarist Bobby Schneck (replaced as of the Apocalyptic Love tour with Frank Sidoras), bassist Todd Kerns (formerly of Age of Electric), and drummer Brent Fitz (formerly of Theory of a Deadman). In late 2010, Kennedy and Slash appeared on That Metal Show, a talk show on VH1 Classic. On November 14, 2011, Slash released a concert film and live album titled Made in Stoke 24/7/11 featuring Kennedy and the rest of his band. Slash's second solo album featured Myles Kennedy, this time as the sole vocalist. It was also announced that band mates Bobby Schneck, Todd Kerns, and Brent Fitz, along with Slash, would complete the lineup for the album. In an interview with MusicRadar, Slash confirmed that it would be less of an actual solo album and more of a collaboration album with Kennedy, and that he was not sure if the album will be billed to Slash or a new name entirely. As of December 2011, three songs had been recorded: "Halo", "Standing in the Sun", and "Bad Rain". Slash has described the music as "very heavy". The album was released on May 22, 2012. A behind-the-scenes video was also released with this announcement. Titled Apocalyptic Love, the album will be billed to "Slash featuring Myles Kennedy and the Conspirators", featuring Kennedy, Kerns, and Fitz as members of Slash's band. The band performed the album in its entirety on April 11, 2012, at the Revolver Golden God Awards. The first single, "You're a Lie", was released to rock radio on February 27, 2012; a 30-second preview of the song was released online. Kennedy has reportedly said that some of the lyrics on the album are about his earlier experiences with drugs. On April 14, 2012, Kennedy performed three Guns N' Roses songs with five former members of Guns N' Roses during their Rock and Roll Hall of Fame induction in Axl Rose's absence. In 2013, he also toured with Kings of Chaos, along with Slash and other ex-Guns N' Roses members. The band's second collective album World on Fire is produced by Michael "Elvis" Baskette and was released on September 16, 2014.

input: Usher developed a friendship with American record producer, Jermaine Dupri, with whom he co-wrote and produced several tracks for his second album, My Way, released on September 16, 1997. The album's lead single, "You Make Me Wanna...", reached number one in the United Kingdom, becoming Usher's first record to be top single; the record led to his popularity reaching in the country. It also became Usher's first gold- and platinum-certified single in the United States. The album's second single, "Nice & Slow", peaked in January 1998 at number one on the Billboard Hot 100, giving Usher his first US number-one single. In February of the same year, the single was certified platinum by the RIAA. My Way has been certified six-time platinum in the United States. "You Make Me Wanna..." won the Best Male R&B/Soul Single at the 1999 Soul Train Music Awards. In the closing months of 1997, Usher embarked on a series of tour engagements including a spot on Puffy's No Way Out tour, dates with Mary J. Blige, and the opening spot on Janet Jackson's The Velvet Rope Tour. Usher's first concert album, Live, was released in 1999, which featured appearances by Lil' Kim, Jagged Edge, Trey Lorenz, Shanice, Twista and Manuel Seal; the album has been certified gold in the United States. Usher made his acting debut on the UPN television series Moesha, which resulted in a recurring role on the series and subsequently his first film role in 1998's The Faculty. Usher's extracurricular activities outside of the recording industry gathered momentum over the following year as he was cast in the soap opera, The Bold and the Beautiful. He completed two more films, She's All That, and his first starring role in Light It Up. He also appeared in the Disney TV movie Geppetto. Usher's third studio album, originally titled All About U, was slated to be released in early 2001. The first single, "Pop Ya Collar", was released in late 2000 and became a number two hit in the UK but underperformed in the United States. The album was subsequently pushed back and retooled after select tracks were later leaked to the radio and Internet. After having revised and renamed to 8701, the album was released August 7, 2001 (8.7.01). The first two singles "U Remind Me" and "U Got It Bad" each topped the Billboard Hot 100 for four and six weeks, respectively. 8701 has been certified four-time platinum in the United States. Usher appeared in the 2001 film Texas Rangers. In February 2002, Usher won a Grammy for Best Male R&B Vocal Performance for "U Remind Me". The next year, he won the same award for "U Don't Have to Call", making Usher the only artist aside from Luther Vandross and Stevie Wonder to win this award consecutively. In summer 2002, Usher contributed vocals to P. Diddy's "I Need a Girl, Part I". The year closed out with a trio of TV series appearances, all in November, on The Twilight Zone, 7th Heaven, Moesha, and American Dreams, the latter in which Usher portrayed Marvin Gaye.
