They have released two studio albums, "St. Elsewhere" (2006) and "The Odd Couple" (2008).  "St. Elsewhere" was recorded on the Warner Music UK label, and contained their hit single "Crazy" which topped at number two on the US Hot 100, and topped the charts in the UK.  It was also nominated at the 2007 Grammy Awards for Record of the Year, and was platinum certified for shipping over 1,000,000 records.  "The Odd Couple" was recorded on Downtown Records label, and was scheduled for release in April 2008, but due to a leak of their album over the internet, they were forced to release it early.  The album in its entirety received good reviews, but did not have as much commercial success as their first album. The Joy Formidable is a Welsh alternative rock band, formed in 2007 in North Wales and currently based in London, England.  The band consists of Rhiannon "Ritzy" Bryan (lead vocals, guitar), Rhydian Dafydd (bass, vocals) and Matthew James Thomas (drums, percussion). The Johnson Girls are an all-female a-cappella song group based in New York City.  They specialize in maritime music and perform songs from a melange of cultures including the United States, Britain, Ireland, Italy and French-Canada.  Named after a traditional African-American sea shanty (maritime work song), "The Johnson Girls," they formed as a quintet in 1997.  The original members were Joy Bennett, Maggie Bye, Alison Kelley, Bonnie Milner, and Dierdre Murtha.  Bye left the group after following the release of The Johnson Girls' second CD.  Each of The Johnson Girls is also a member of the official maritime song group of South Street Seaport Museum, The New York Packet.

Ah Ni 阿妮, formerly known as Xiao Ni Ni 小妮妮), Crystal Ong Shir Ching(王雪晶), and Cass Chin Yan Zi (陳金燕), who left in 2005 to study but later came back in late 2012.  Their albums are sold in Malaysia, Singapore, China, Indonesia, the United States and in some other parts of the world.  In some countries, only their bootlegged albums can be found.  Due to the increased popularity of online streaming and unlicensed albums, their company StarMedia decided to stop producing Chinese New Year Albums by M-Girls, with their final Chinese New Year album titled "True Joy".  Their final performance as a group was on 23 February 2014, a couple of weeks after the release of their Mini Album, My Way.  Although Angeline moved to China to study, the remaining members continued to promote their latest album.  It was later confirmed that M-Girls would be releasing another CNY album for 2015 called 新春佳期 which translates to New Spring Holiday Pre-orders for their latest Chinese New Year album was announced through social media on 18 November 2016, titled 过年要红红 which roughly translates to The New Year Needs to be Red and will mark the first time Crystal has not released a Chinese New Year album since her debut in 1994. The Mark of Cain (also seen as the initialism, TMOC) are a hard rock, alternative metal band from Adelaide, South Australia.  Their style has been likened to that of Helmet and Rollins Band, yet this band pre-dates both groups and was influenced by the early work of Joy Division, Big Black and United States hardcore groups.  The Mark of Cain were formed in mid-1984 by brothers, John (guitar) and Kim Scott (bass guitar), with Rod Archer on vocals and Gavin Atkinson playing drums.  Before long, Archer had left the group and John Scott took on the lead vocal role and the group has remained a trio ever since.  The Scotts have been the core of the band which has featured 15 different drummers.  Since January 2001, former Helmet member John Stanier has been their drummer; he is also concurrently with Tomahawk and Battles.  Australian musicologist, Ian McFarlane, described the group's sound as "Gloomy, monotonous vocals and bleak slabs of metallic guitar did battle over a lurching rhythm section to arrive at a harsh sound."  Rod Archer died on 26 February 2016. Ibn Bey (22 March 1984 – 10 December 2012) was a British-bred Thoroughbred racehorse and sire who won major races in the United Kingdom, France, Ireland, Italy and Germany as well as competing in the United States and Japan.  After winning once as a two-year-old in 1986 he won the Predominate Stakes in 1987 before recording his first Group One success in the Gran Premio d'Italia.  He continued to improve with age and developed into a formidable international campaigner over long distances winning the Grand Prix de Deauville, Prix Maurice de Nieuil, Geoffrey Freer Stakes, Preis von Europa, Grosser Preis von Berlin and Irish St Leger.  On his penultimate start he produced arguably his best performance when finishing second in the Breeders' Cup Classic.  He was retired from racing to become a breeding stallion in Japan where he had limited impact as a sire of winners.  He died in Japan in December 2012.
