IN: Tangerine Dream is a German electronic music band founded in 1967 by Edgar Froese. The group has seen many personnel changes over the years, with Froese being the only continuous member until his death in January 2015. The best known line-up of the group was its mid-70s trio of Froese, Christopher Franke, and Peter Baumann. In the late 1970s, Johannes Schmoelling replaced Baumann.

Edgar Froese arrived in West Berlin in the mid-1960s to study art. His first band, the psychedelic rock-styled The Ones, disbanded after releasing only one single. After The Ones, Froese experimented with musical ideas, playing smaller gigs with a variety of musicians. Most of these performances were in the famous Zodiak Free Arts Lab, although one grouping also had the distinction of being invited to play for the surrealist painter Salvador Dali. The music was partnered with literature, painting, early forms of multimedia, and more. It seemed as though only the most outlandish ideas attracted any attention, leading Froese to comment, "In the absurd often lies what is artistically possible." As members of the group came and went, the direction of the music continued to be inspired by the Surrealists, and the group came to be called by the surreal-sounding name of Tangerine Dream, inspired by the line "tangerine trees and marmalade skies" from The Beatles' track "Lucy in the Sky with Diamonds." Froese was fascinated by technology and skilled in using it to create music. He built custom-made instruments and, wherever he went, collected sounds with tape recorders for use in constructing musical works later. His early work with tape loops and other repeating sounds was the obvious precursor to the emerging technology of the sequencer, which Tangerine Dream quickly adopted upon its arrival. The first Tangerine Dream album, Electronic Meditation, was a tape-collage Krautrock piece, using the technology of the time rather than the synthesized music they later became famous for. The line-up for the album was Froese, Klaus Schulze, and Conrad Schnitzler. Electronic Meditation was published by Ohr in 1970, and began the period known as the Pink Years (the Ohr logo was a pink ear). But starting with their second album, Alpha Centauri, the group has been a trio or occasionally duo of electronic instruments, commonly augmented by guitar from Froese (or, much later, other musicians as well), and occasionally also other instruments. Of these, drums from Christopher Franke and organ from Steve Schroyder (on Alpha Centauri) or Peter Baumann (on subsequent releases) feature prominently in the band's music during the early 70s. They also started their heavy usage of the Mellotron during this period.

IN: Philip Glass (born January 31, 1937) is an American composer. He is widely regarded as one of the most influential musicians of the late 20th century. Glass's work has been described as minimal music, having similar qualities to other "minimalist" composers such as La Monte Young, Steve Reich, and Terry Riley. However, Glass has instead described himself as a composer of "music with repetitive structures", which he has helped evolve stylistically.

In the late 1990s and early 2000s, Glass's lyrical and romantic styles peaked with a variety of projects: operas, theatre and film scores (Martin Scorsese's Kundun, 1997, Godfrey Reggio's Naqoyqatsi, 2002, and Stephen Daldry's The Hours, 2002), a series of five concerts, and three symphonies centered on orchestra-singer and orchestra-chorus interplay. Two symphonies, Symphony No. 5 "Choral" (1999) and Symphony No. 7 "Toltec" (2004), and the song cycle Songs of Milarepa (1997) have a meditative theme. The operatic Symphony No. 6 Plutonian Ode (2002) for soprano and orchestra was commissioned by the Brucknerhaus, Linz, and Carnegie Hall in celebration of Glass's sixty-fifth birthday, and developed from Glass's collaboration with Allen Ginsberg (poet, piano - Ginsberg, Glass), based on his poem of the same name. Besides writing for the concert hall, Glass continued his ongoing operatic series with adaptions from literary texts: The Marriages of Zones 3, 4 and 5 ([1997] story-libretto by Doris Lessing), In the Penal Colony (2000, after the story by Franz Kafka), and the chamber opera The Sound of a Voice (2003, with David Henry Hwang), which features the Pipa, performed by Wu Man at its premiere. Glass also collaborated again with the co-author of Einstein on the Beach, Robert Wilson, on Monsters of Grace (1998), and created a biographic opera on the life of astronomer Galileo Galilei (2001). In the early 2000s, Glass started a series of five concerti with the Tirol Concerto for Piano and Orchestra (2000, premiered by Dennis Russell Davies as conductor and soloist), and the Concerto Fantasy for Two Timpanists and Orchestra (2000, for the timpanist Jonathan Haas). The Concerto for Cello and Orchestra (2001) had its premiere performance in Beijing, featuring cellist Julian Lloyd Webber; it was composed in celebration of his fiftieth birthday. These concertos were followed by the concise and rigorously neo-baroque Concerto for Harpsichord and Orchestra (2002), demonstrating in its transparent, chamber orchestral textures Glass's classical technique, evocative in the "improvisatory chords" of its beginning a toccata of Froberger or Frescobaldi, and 18th century music. Two years later, the concerti series continued with Piano Concerto No. 2: After Lewis and Clark (2004), composed for the pianist Paul Barnes. The concerto celebrates the pioneers' trek across North America, and the second movement features a duet for piano and Native American flute. With the chamber opera The Sound of a Voice, Glass's Piano Concerto No. 2 might be regarded as bridging his traditional compositions and his more popular excursions to World Music, also found in Orion (also composed in 2004).
