Question:
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.

Answer:

Answer the question at the end by quoting:

"Bohemian Rhapsody" is a song by the British rock band Queen. It was written by Freddie Mercury for the band's 1975 album A Night at the Opera. It is a six-minute suite, consisting of several sections without a chorus: an intro, a ballad segment, an operatic passage, a hard rock part and a reflective coda. The song is a more accessible take on the 1970s progressive rock genre.
I'm going to shatter some illusions, it was just one of those pieces I wrote for the album: just writing my batch of songs. In its early stages I almost rejected it, but then it grew. We started deciding on a single about halfway through. There were a few contenders - we were thinking of "The Prophet's Song" at one point - but then "Bohemian Rhapsody" seemed the one. There was a time when the others wanted to chop it around a bit, but I refused. If it was going to be released, it would be in its entirety. We knew it was very risky, but we had so much confidence in that song - I did anyway. I felt, underneath it all, that if it was successful it would earn a lot of respect. People were all going, You're joking, they'll never play it, you'll only hear the first few bars and then they'll fade it out. We had numerous rows. EMI were shocked - a six-minute single? You must be joking! The same in America - oh, you just got away with it in Britain. When we finished the album, the Night at the Opera album, that was the track on it that we thought we were gonna release as a single in the UK first. And when we released it in Britain we didn't necessarily think it'd be released in America, cause we know even over here, you know, the AM tastes are even more [hesitates] stricter. Anyway we did have thoughts about even in the UK, perhaps editing it down at all, but we listened to it over and over again and there was no way we could edit it. We tried a few ideas, but if you edited it, you always lost some part of the song, so we had to leave it all in. And luckily it took off anyway. The vocal harmonies was something we wanted to do from the beginning, as we are always keen to do that kind of thing. We wanted to be a group that could do the heaviness of hard rock, but also have harmonies swooping around all over the place. We thought there was some real power and emotion in that combination. The guitar solo was pretty much off the cuff, except I think I had plenty of time to think about that one. I remember playing along with it in the studio for a while when other things were being done. I knew what kind of melody I wanted to play.
