Italian producer Mario Dradi conceived the idea of the first concert in 1990 in Rome. It was held to raise money for Carreras's foundation, the José Carreras International Leukemia Foundation. It was also for his friends Domingo and Pavarotti a way to welcome Carreras back into the world of opera after undergoing successful treatment for leukemia.

The three subsequently sang together in concerts at Dodger Stadium in Los Angeles to coincide the final match of the 1994 FIFA World Cup, at the Champ de Mars under the Eiffel Tower during the 1998 FIFA World Cup, and in Yokohama for the 2002 FIFA World Cup. They also toured other cities around the world, usually performing in stadiums or similar large arenas to huge audiences. Nearly 50,000 people attended their 1994 concert at Dodger Stadium.

A second series of concerts outside of the FIFA World cup events held again in 1999 including cities like Tokyo, Pretoria and Detroit followed by a Christmas concert in Vienna in December the same year. In 2000 the Three Tenors toured again performing live in San Jose, California, Las Vegas, Washington, D.C., Cleveland and São Paulo. One more benefit concert was given by The Three Tenors in December 2000 in Chicago to donate the AIDS Foundation of Chicago. In 2001 two more concerts was given in Asia one in Seoul and one in Beijing inside the walls of the Forbidden City. Finally in 2003 they performed in Bath at the Royal Crescent and later in September the same year they gave their last Three Tenors' concert, which took place at the Schottenstein Center in Columbus, Ohio.

The concerts were a huge commercial success, and were accompanied by a series of best-selling recordings: The Three Tenors In Concert (which holds the Guinness World Record for the best-selling classical music album), The Three Tenors in Concert 1994, The Three Tenors: Paris 1998, The Three Tenors Christmas, and The Best of The Three Tenors. Zubin Mehta conducted the performances in 1990 and 1994. The Paris concert was conducted by James Levine.

The Three Tenors repertoire ranged from opera to Broadway to Neapolitan songs and pop hits. The group's signature songs included "Nessun dorma" from Puccini's opera Turandot, usually sung by Pavarotti, and the ballad "O Sole Mio", which all three tenors typically sang together. Wikipedia
