Document 2: Triple Quartet: Triple Quartet is a piece written by Steve Reich in 1998. It was commissioned by and is dedicated to the Kronos Quartet, and was premiered by them on May 22, 1999 in the Kennedy Center, Washington DC.
Document 3: The Cave (opera): The Cave is a multimedia opera in three acts by Steve Reich to an English libretto by his wife Beryl Korot. It was first performed in 1993 in Vienna by the Steve Reich Ensemble, conducted by Paul Hillier. The title "The Cave" refers to The Cave of the Patriarchs in Hebron, where Abraham and Sarah (and several other major religious figures) are buried.
Document 4: Sextet (Reich): Sextet is a composition by Steve Reich. As the title indicates, it is written for an ensemble of six: four percussionists and two keyboardists. The percussionists play (at various times) three marimbas, two vibraphones, two bass drums, crotales, sticks, and tam-tam. Two percussionists double on piano during the opening "Pulse" section. The keyboardists play both pianos and synthesizers set to an electric organ sound. The piece was composed in 1984–1985 and is about 28 minutes in duration.
Document 5: Drumming (Reich): Drumming is a piece by minimalist composer Steve Reich, dating from 1970–1971. Reich began composition of the work after a short visit to Ghana and observing music and musical ensembles there, especially under the Anlo Ewe master drummer Gideon Alorwoyie. His visit was cut short after contracting malaria. K. Robert Schwarz describes the work as "minimalism's first masterpiece."
Document 6: Holy Spirit Grotto: The Holy Spirit Grotto ("La Gruta del Espíritu Santo" in Spanish), also known as Corinto Cave, in Corinto, Morazán, El Salvador, is a registered national monument of petroglyphs. The cave is largely associated with the Xibalba legend. The archaeologist Wolfgang Haberland performed studies in the late 1970s indicating the art belongs to the pre-Classic stage of Mesoamerican civilization. The cave likely got its name due to the Mesoamerican association of caves with the underworld, meaning that they are "considered an entrance to the underground world governed by spirits and deities of death, disease, water, and fertility." The cave is an important cultural and religious site for the Lenca nation, forming part of their traditions and legends of the place where ancestors of Balam Colop parted (which is mentioned in the Popol vuh), according to their legends and traditions, is father of all Lenca people, given the association of caves with the underworld by Mesoamericans, the name of 'Holy Spirit Cave' is ironic and perhaps an attempt by early Spanish to "exorcise" the cave in El Salvador. The "holy" nature of this cave is further confirmed by a man named Don Argelio Alvarez, who happens to be one of its guardians. Roughly translated, he claims that the cave contains "something magical and inexplicable that inspires tranquility and peace." Many people from various religious groups also continue to visit the site and carry out ceremonies, such as what Don Argelio believed to have taken place in the cave many centuries ago. However, it is entirely possible that the cave was instead used for other means. A German scientist found some handcrafted arrows and knives made of obsidian within the cave, leading him to believe that it may have actually been a shelter for hunters instead.

The former is housed in the Norfolk's Hermitage Museum, and the latter is in the private collection of Sir Andrew Lloyd Webber.
