The Dells were an American R&B vocal group.
 Formed in high school in 1952 by founding members Marvin Junior, Verne Allison, Johnny Funches, Chuck Barksdale, and Mickey and Lucius McGill, under the name the El-Rays, they released their first recording in 1954, and two years later, had their first R&B hit with "Oh What a Night".
 After disbanding due to a near-fatal car crash in 1958, the band reformed in 1960 with Funches being replaced by Johnny Carter.
 This lineup remained together until Carter's 2009 death.
 The Dells were inducted to the Rock and Roll Hall of Fame and the Vocal Group Hall of Fame in 2004.
 The vocal group performed until illness forced longtime lead singer Marvin Junior and bass vocalist Chuck Barksdale into retirement, ending the group's 60-year run.
The Texas Tenors are a 3-time Emmy Award winning classical crossover, trio vocal group formed in 2009 by country music singer JC Fisher, pop singer Marcus Collins and opera singer John Hagen.

 In December, the band went on an east coast tour with This Is Hell, Evergreen Terrace and Casey Jones.
 Videos have been released for "Cake Eater" and "Nothing But a Ghost".
 The album is the group's last record with Kevin Skaff and Derek Smith.
The Platters is an American vocal group.
 They were one of the most successful vocal groups of the early rock and roll era.
 Their distinctive sound was a bridge between the pre-rock Tin Pan Alley tradition and the burgeoning new genre.
 The act went through several personnel changes, with the most successful incarnation comprising lead tenor Tony Williams, David Lynch, Paul Robi, Herb Reed, and Zola Taylor.
 The group had 40 charting singles on the "Billboard" Hot 100 chart between 1955 and 1967, including four no. 1 hits.
 The Platters were one of the first African American groups to be accepted as a major chart group and were, for a period of time, the most successful vocal group in the world.
Havin' a Ball at the Village Gate is the third and final album by the reformed jazz vocal group Lambert, Hendricks & Bavan, of Dave Lambert and Jon Hendricks with Yolande Bavan.
 The group was formed after Annie Ross left the vocal group in 1962.

The This Is Us Tour was the eighth concert tour by American boy band, the Backstreet Boys.

 The tour reached Europe, Asia, Australasia and the Americas.
 The tour was the second concert tour the band had performed as a quartet.
Acappella Vocal Band (AVB) was a vocal group put together by Keith Lancaster in 1986 to augment the vocal group Acappella.
 AVB's popularity and ministry quickly grew, prompting Lancaster to launch AVB as a full-time touring group in 1988.
 AVB went through various lineup and stylistic changes before disbanding in 2000.
The Backstreet Boys (often abbreviated as BSB) are an American vocal group, formed in Orlando, Florida in 1993.

Diana Ernestine Earle Ross (born March 26, 1944) is an American singer, songwriter, actress, and record producer.
 Born and raised in Detroit, Michigan, Ross rose to fame as the lead singer of the vocal group The Supremes, which, during the 1960s, became Motown's most successful act, and is to this day the United States' most successful vocal group, as well as one of the world's best-selling girl groups of all time.
 Ross' success as lead singer of The Supremes made it possible for future African-American R&B and soul acts to find mainstream success.
 The group released a record-setting twelve number-one hit singles on the US "Billboard" Hot 100, including "Where Did Our Love Go", "Baby Love", "Come See About Me", "Stop!
 In the Name of Love", "You Can't Hurry Love", "You Keep Me Hangin' On", "Love Child", and "Someday We'll Be Together".
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.
