Seether are a South African rock band founded in May 1999 in Pretoria, Gauteng, South Africa. The band originally performed under the name Saron Gas until 2002, when they moved to the United States and changed it to Seether to avoid confusion with the deadly chemical known as sarin gas. Disclaimer is their original album and major label debut. They gained mainstream popularity in 2002 with their US Active Rock number one single "Fine Again", and their success was sustained in 2004 with the single "Broken" which peaked at number 20 on the Billboard Hot 100.
The band spent several months recording in Nashville, Tennessee with producer Brendan O'Brien, then resumed touring in April 2010 with the intention of returning to the studio "in the first week of June" to complete the new record. Drummer John Humphrey confirmed in August that recording was completed, and the album was in the mixing process. He said that the band believed this album to be their best work, and that the songs are "very strong, melodic, and heavy at times." Morgan confirmed the album's completion in September, and gave the expected release date as early 2011. A new song, "No Resolution", was debuted on 4 September 2010, during a live show at the DuQuoin, IL State Fair. McLawhorn and Humphrey, in a radio interview, announced that the new album would be titled Holding Onto Strings Better Left to Fray, and that it would be released in May. The album's first single, "Country Song", was released on 8 March in the US and on 4 April in the United Kingdom, and the new album was released on 17 May 2011. Seether reached their highest position on the US Billboard 200 Charts when Holding On to Strings Better Left to Fray rose to the Number 2 position. It also reached number one on the US Rock Albums, US Alternative Albums and US Hard Rock Album Charts. Their single-week sales of 61,000 records was their best since Karma and Effect sold 82,000 copies in 2005. Billboard named Seether the No. 1 Active and No. 1 Heritage Rock Artist of 2011. A remix EP of the Holding Onto Strings Better Left to Fray album, titled Remix EP, was released on 7 February 2012. Troy McLawhorn's departure from the band and return to Evanescence was announced on 8 March. Seether performed live in Cincinnati, Ohio on 10 May, and in South Bend, Indiana on 11 May. Both concerts were recorded, and released as a limited edition CD set for each individual city. Seether played main stage on the Uproar Festival alongside bands Avenged Sevenfold, Three Days Grace, Bullet For My Valentine, and Escape The Fate, and supported 3 Doors Down on their European tour from November to March. On 3 September 2013, the band announced the name of a compilation album, titled Seether: 2002-2013. The album was released on 29 October 2013 as a 2-disc album, featuring some of Seether's greatest hits, unreleased demos, soundtrack songs, and 3 all-new tracks, including a cover of Veruca Salt's "Seether" (the song that the band is named after). Seether: 2002-2013 also contains two new recorded songs ("Safe To Say I've Had Enough" and "Weak") and was produced by Brendan O'Brien. The band released a 15-second demo clip for the song "Safe To Say I've Had Enough" on loudwire.com. The band also carried out a small, semi-acoustic tour of Europe and South Africa. On 30 November 2013 Seether released a 3-track single "Goodbye Tonight" featuring Van Coke Kartel & Jon Savage. The song is also featured on Deluxe edition of "Isolate and Medicate".

Their single-week sales of 61,000 records was their best since Karma and Effect sold 82,000 copies in 2005.

IN: Bobby Darin (born Walden Robert Cassotto; May 14, 1936 - December 20, 1973) was an American singer, songwriter, multi-instrumentalist, and actor in film and television. He performed jazz, pop, rock and roll, folk, swing, and country music. He started his career as a songwriter for Connie Francis.

Born Walden Robert Cassotto in the East Harlem neighborhood of New York City, Bobby Darin was reared by his maternal grandmother, whom he believed was his mother. Darin's birth mother, Vanina Juliette "Nina" Cassotto (born November 30, 1917), became pregnant with him in the summer of 1935 when she was 17. Presumably because of the scandalous nature of out-of-wedlock pregnancies in that era, Nina and her mother hatched a plan to pass her baby off as Nina's younger brother. Years later, when Nina finally told Darin the truth about his upbringing, she refused to reveal the identity of his biological father, and kept the secret to her death in 1983. Darin's maternal grandfather, Saverio Antonio "Big Sam Curly" Cassotto (born January 26, 1882), was of Italian descent and a would-be mobster who died in prison from pneumonia a year before Darin's birth. His maternal grandmother, Vivian Fern Walden (also born in 1882), who called herself Polly, was of English ancestry and a vaudeville singer. From his birth, Darin always believed Nina to be his older sister and Polly his mother. But in 1968, when he was 32, Nina told Darin the truth, reportedly devastating him. By the time he was a teenager, Darin could play several instruments, including piano, drums, and guitar. He later added harmonica and xylophone. Darin moved to the Bronx early in his life (with a rented summer home in Staten Island) and graduated from the prestigious Bronx High School of Science. In later years he attributed his arrogance to his experiences there, where he was surrounded by brighter students who teased him. He then enrolled at Hunter College and soon gravitated to the drama department. After only two semesters, he dropped out to pursue an acting career.
