Question: What is a collaboration between the Irish band and many top country music musicians including a singer known for her soprano singing range and her country pop material ?
Context: Country pop is a subgenre of country music and pop music that was developed by members of the Country genre out of a desire to reach a larger, mainstream audience.  By producing country songs that employed many styles and sounds found in pop music, the country music industry was effective in gaining new listeners without alienating its traditional country audience.  Country pop music is often known for genres like rock, pop, and country combined.  It is a continuation of similar efforts that began in the late 1950s originally known as Nashville sound and later on Countrypolitan.  By the mid-1970s, many country artists were transitioning to the pop-country sound which led to some records charting high on mainstream top 40 as well as country "Billboard" charts. American country artist Crystal Gayle has released fifteen music videos and sixty-eight singles.  The latter includes six promotional singles, three singles as a collaborative artist, and five singles as a featured artist.  Gayle's debut single was 1970's "I've Cried (The Blue Right Out of My Eyes)" via Decca Records, which reached the top-forty of the "Billboard" Hot Country Singles chart.  Encouraged by her sister to develop her own musical style, Gayle signed with United Artists Records where she began recording country pop material.  That year "Wrong Road Again" reached the sixth position on the country songs chart, launching several major country hits including "I'll Do It All Over Again", and her first number one hit "I'll Get Over You".  Gayle released "Don't It Make My Brown Eyes Blue" in 1977 which became her signature song and brought her crossover pop success.  It topped the country songs chart, reached number two on the Billboard Hot 100, and became an international hit.  Its success elevated Gayle's career and was followed by three more number one country singles: "Ready for the Times to Get Better", "Why Have You Left the One You Left Me For", and the top-twenty pop hit "Talking in Your Sleep". Vũ Thu Minh (born September 22, 1977) often known simply as Thu Minh, is a Vietnamese pop-singer.  She is famous for pop ballads and dance-pop music and is referred to as the "Queen of Dance-pop in Vietnam".  Thu Minh is also called "Vietnam's Celine Dion" and "The wind chime of Vietnamese music" due to her famous and rare soprano C or Spinto soprano singing voice that has a range from D3 (low) to C7 (high) with the highest belt note B5, headvoice C#6, and some whistle.  She originally trained to be a ballet dancer, and, before the age of 30, she had never taken officially any professional music school. Voice of Ages is a 2012 album by The Chieftains.

The young duo quickly emerged after several years starting their careers by making covers.  Their music has been tagged as bro-country, transitioning from the traditional country feel to their hybrid sounds and their lyrical focus about backroads, girls, alcoholic drinks and trucks.  Their 2012 debut single "Cruise" became a smash hit, breaking two records.  "Cruise" was downloaded over seven million times, making it the first country song ever to receive the Diamond certification, and the best-selling digital country song of all time with 24 weeks at number one until it was surpassed in July 2017 by Sam Hunt's "Body Like a Back Road".

In December 2011, they signed a publishing, production and management deal with Big Loud Mountain, Craig Wiseman's (Big Loud Shirt Publishing), Joey Moi's (Mountain View Records), and Kevin "Chief" Zaruk's partnership.  Their second EP, "It'z Just What We Do", charted on the "Billboard" Top Country Albums chart.  They played on the 2012 Country Throwdown Tour, along with acts such as Josh Thompson, Corey Smith, Gary Allan, Justin Moore, and Rodney Atkins.
