Question: Tarja Soile Susanna Turunen-Cabuli (born 17 August 1977), known professionally as Tarja Turunen or simply Tarja, is a Finnish singer-songwriter. She is a soprano and has a vocal range of three octaves. Turunen studied singing at Sibelius Academy and Hochschule fur Musik Karlsruhe. She is a professional classical lied singer, and the former lead vocalist of the Finnish symphonic metal band Nightwish, which she founded with Tuomas Holopainen and Emppu Vuorinen in 1996.

Turunen's voice is described by critics as remarkably powerful and emotional. Sometimes it is stated that her voice is too trained or operatic for metal music, but even critics who do not like classical voices admit that her voice suits the kind of metal songs she sings unusually well.  Until the end of their collaboration, Turunen's singing was a trademark of Nightwish. She was known as the face and voice of Nightwish while bandleader Holopainen was the soul. Turunen was seen as a key to Nightwish's success. She is respected by other musicians of the metal genre and is an influence on their work; for instance, Simone Simons of Epica names her as her inspiration to study classical music and apply that vocal style to a metal band.  Turunen receives most of her media attention in Europe, especially in her home of Finland. In December 2003, she was invited by Finnish president Tarja Halonen to celebrate the Finnish Independence Day at the Presidential Palace together with other Finnish celebrities. The event is televised annually live by the state-owned broadcaster, the Finnish Broadcasting Company. In December 2007, she performed different versions of the Finnish national anthem "Maamme" (Finnish: "Our country") accompanied by the Tapiola Sinfonietta, to celebrate the 90th anniversary of Finnish independence. The concert was televised by the Finnish Broadcasting Company for 2 million Finnish viewers. In December 2013, Turunen was the invited soloist at the Christmas Peace event in the Turku Cathedral, Finland, with the presence of Finnish president Sauli Niinisto. The concert aired on Yle TV1 at the Christmas Eve. During her solo career, Turunen has sold over 100,000 certified records in Finland, which places her among the top 50 of best-selling female soloists.  In Europe, her popularity is mainly limited to the hard rock and metal scene. She had a broader exposure on November 30, 2007, when she was invited to open the farewell fight of Regina Halmich. Her performance of "I Walk Alone" was televised live by the German television station ZDF for 8.8 million viewers. Turunen will be one of the star coaches in the fourth season of The Voice of Finland in the spring of 2015 on Nelonen. After the success of the 2015 edition of The Voice of Finland, Tarja was again chosen to be one of the star coaches for the 2016 edition.

Question: Ahmet Ertegun (, Turkish spelling: Ahmet Ertegun ([ah'met erte'jyn]); (July 31 [O.S. 18 July] 1923 - December 14, 2006) was a Turkish-American businessman, songwriter and philanthropist. He was best known as the co-founder and president of Atlantic Records, and for discovering and championing many leading rhythm and blues and rock musicians. He also wrote classic blues and pop songs, and served as the chairman of the Rock and Roll Hall of Fame and museum, located in Cleveland, Ohio. Ertegun has been described as "one of the most significant figures in the modern recording industry."

A memorial service for Ertegun was held in New York on April 17, 2007. A large part of the evening was given over to musical performances. Wynton Marsalis opened the tribute with the jazz standard "Didn't He Ramble", Eric Clapton and Dr. John performed "Drinkin' Wine Spo-Dee-O-Dee", and other performers included Solomon Burke, Ben E. King, Sam Moore, Stevie Nicks, Crosby, Stills, Nash & Young, and Phil Collins.  Another informal salute to him took place in Los Angeles on July 31, 2007, the anniversary of his birth. The tribute took place at Grauman's Egyptian Theatre in Hollywood. Several of his friends shared anecdotes about their experiences with him and the assembled gathering then saw a special screening of the American Masters documentary Atlantic Records: The House That Ahmet Built. Among those who paid tribute to Ertegun in person were: Solomon Burke, Jerry Leiber & Mike Stoller, Keith Emerson, Peter Asher, Spencer Davis, the film's producer (and longtime friend) Phil Carson, Taylor Hackford and event producer Martin Lewis. Yusuf Islam, formerly known as Cat Stevens, came to America after a 20-year hiatus to attend the ceremonies.  The Martin Scorsese film "Shine a Light" about The Rolling Stones concert held at the Beacon Theatre in New York contains a dedication to Ertegun and Andrea Corr's solo album Ten Feet High is dedicated "To the memory of Ahmet Ertegun".  In honor of the barriers the Ertegun brothers broke during their time in segregated Washington, the current Turkish Ambassador to the U.S., Namik Tan, hosts a series of jazz concerts at the historical residence on Sheridan Circle in Washington, D.C. The "Ertegun Jazz Series," in collaboration with Jazz at Lincoln Center, revives the brothers' legacy of bridging cultures and bringing people together with one common objective: celebrating music. In that same spirit, Ambassador Tan is opening the doors of his home to residents of D.C. from various backgrounds - Members of Congress, Administration officials, academia, the media, business leaders, and others.
