Problem: Najm was born and raised in Tallahassee, Florida. His stage name is short for "Tallahassee Pain", and was chosen because of the hardships he experienced while living there. Najm was brought up in a Muslim household, but he has expressed his lack of interest in the concept of religion. At just three years old he got his first taste of the music business when a friend of the family, gospel jazz artist/producer Ben Tankard, allowed him to spend time and "twist the knobs" at his recording studio.

In 2007, T-Pain began work on his third album with Rocco Valdes, Akon and Lil Wayne. The album was also his first under his Nappy Boy Entertainment.  T-Pain's third studio album, Thr33 Ringz, was released on November 11, 2008. The album sold 168,000 records in its first week, reaching number four on the Billboard 200. A mixtape, Pr33 Ringz, was released in early 2008 before the album.  The album was preceded by three singles. Its lead single, "Can't Believe It", featuring Lil Wayne, was released in July 2008. The single reached number seven on the Hot 100 and number two on the Hot R&B/Hip-Hop Songs chart. The album's second single, "Chopped 'N' Skrewed", featuring Ludacris, was released in September 2008. The single reached number twenty-seven on the Hot 100 and number three on the Hot R&B/Hip-Hop Songs chart. The third and final single from the album, "Freeze", featuring Chris Brown, was released in October 2008 and reached number thirty-eight on the Hot 100 and number thirty-nine on the Hot R&B/Hip-Hop Songs chart. Guest appearances on Thr33 Ringz included T.I., Lil Wayne, Ludacris, DJ Khaled, Ciara, Chris Brown and Kanye West among others. Pr33 Ringz was the introduction mixtape for the album.  In 2008, T-Pain continued to appear on numerous rap singles, such as "She Got It" by 2 Pistols, "Go Girl" by Ciara, "The Boss" by Rick Ross, "Cash Flow" by Ace Hood, "Shawty Get Loose" by Lil Mama, "One More Drink" by Ludacris, and "Go Hard" by DJ Khaled with Kanye West. T-Pain and Ludacris collaborated to perform "Chopped 'N' Skrewed" and "One More Drink" on American late-night television programs Jimmy Kimmel Live! on ABC in November 2008 and on NBC's Saturday Night Live in the same month. T-Pain appeared again on SNL in February 2009 (on the episode hosted by Bradley Cooper with musical guest TV on the Radio) in the SNL Digital Short. T-Pain also supported the album in 2009 with his Thr33 Ringz Tour, which included sold out shows across North America. T-Pain and rapper Lil Wayne formed the duo T-Wayne in 2008. The duo released a self-titled mixtape in late 2008; it charted on the Billboard 200 in January 2009. Their debut album was going to be released in 2009, but never was.  In 2009, T-Pain hosted the BET Awards afterparty and paid tribute to Michael Jackson in West Covina.

Did he go on tour during that time?

Question:
Blood, Sweat & Tears (also known as "BS&T") is a jazz-rock American music group. They are noted for their combination of brass and rock band instrumentation. The group recorded songs by rock/folk songwriters such as Laura Nyro, James Taylor, the Band and the Rolling Stones as well as Billie Holiday and Erik Satie. They also incorporated music from Thelonious Monk and Sergei Prokofiev into their arrangements.
Clayton-Thomas left in early January 1972 to pursue a solo career. He was briefly replaced by Bobby Doyle and then Jerry Fisher, who went on to front the next incarnation of Blood, Sweat & Tears. Fred Lipsius left as well and was briefly replaced by Joe Henderson, before Lou Marini settled into the new lineup. Another founding member, Dick Halligan, also departed, replaced by jazz pianist Larry Willis (from the Cannonball Adderley Quintet), and Swedish guitarist Georg Wadenius, from the popular Swedish outfit Made in Sweden, joined as lead guitarist around the same time.  The new edition of Blood, Sweat & Tears released New Blood in September 1972, which found the group moving into a more overtly jazz-fusion repertoire. The album broke through the Top 40 chart (the last BS&T LP to do so) and spawned a single ("So Long Dixie", chart peak: 44) that received some airplay. Also included on the record was a cover version of Herbie Hancock's "Maiden Voyage", featuring the voice/guitar soloing of Georg Wadenius.  In mid-1973, Katz left to pursue a career as a producer (for Lou Reed and others). Winfield departed as well and was replaced by Tom Malone.  Blood, Sweat & Tears' next album, No Sweat (June 1973), continued in a jazz-fusion vein and featured intricate horn work. Tom Malone's stay in the band was brief and he left to make way for jazz trumpeter John Madrid. But Madrid's tenure was likewise short-lived and he never recorded with the band. Both Madrid and Soloff left in early 1974, making way for new horn player/arranger Tony Klatka on their next release, Mirror Image (July 1974), which also saw the addition of vocalist/saxophonist Jerry LaCroix (formerly of Edgar Winter's White Trash), sax player Bill Tillman, bassist Ron McClure and the exodus of original bass player Jim Fielder. This recording features the adoption of a sound pitched between Philly Soul and the mid-1970s albums by Herbie Hancock's Headhunters, along with aspirations to Chick Corea's jazz-fusion group Return to Forever.  Jerry LaCroix left BS&T to join Rare Earth after playing his final show with them at Wollman Rink in New York's Central Park on July 27, 1974. Luther Kent, a blues singer from New Orleans, was recruited to replace LaCroix.
