"I'll Be Missing You" is a song recorded by American rapper Puff Daddy and singer Faith Evans, featuring R&B group 112, in memory of fellow Bad Boy Records artist (and Evans's husband) Christopher "The Notorious B.I.G." Wallace, who was murdered on March 9, 1997. Released as the second single from Puff Daddy and the Family's No Way Out album, "I'll Be Missing You" samples the Police's 1983 hit song "Every Breath You Take", with an interpolated chorus sung by Evans and interpolated rhythm. The track also features a spoken intro over a choral version of Samuel Barber's "Adagio for Strings". At the 40th Annual Grammy Awards, the song won the Grammy Award for Best Rap Performance by a Duo or Group. The single spent eleven weeks atop the US Billboard Hot 100 and reached number one in 15 other countries; it was the best-performing single of 1997 in Iceland, the Netherlands (Dutch Top 40), and Romania. With shipments of over three million copies in the United States and over one million in both Germany and the United Kingdom, the song has become one of the best-selling singles of all time.
