Elbosco was the name of a joint Spanish musical group that achieved world success with the song Nirvana in 1995.

The group consisted of the boys choral group of the Escolanía del Real Monasterio of San Lorenzo, with boys between 9 and 14 years old along with adult instrumentalists and soloists. In 1995, the group released the disk Angelis, with the hit song Nirvana which was used by Danny Boyle in the film 'Millions'. The music, a mixture of Gregorian chants with hip-hop and techno, with a mixture of Latin and English vocals, attained international fame. They also released a Portuguese version of the disk with the same title. The group mixed classical music, boys chorus and synth generated sounds, resulting in a sound similar to that of Enigma.

In the monastery, 100 boys are selected for their musical talent and presented in white robes.
