Question:
Bradley Joseph (born 1965) is an American composer, arranger, and producer of contemporary instrumental music. His compositions include works for orchestra, quartet, and solo piano, while his musical style ranges from "quietly pensive mood music to a rich orchestration of classical depth and breadth". Active since 1983, Joseph has performed in front of millions of people around the world. He played various instruments in rock bands throughout the Midwest until 1989 when Greek composer Yanni hired him for his core band after hearing a tape of his original compositions.
In 1989, Joseph recorded his first demo tape and sent it off to Greek composer Yanni, who was looking for someone to replace keyboardist John Tesh, as Tesh was launching his own solo career. When Yanni heard Joseph's compositions and arrangements, he was hired over the phone to join his core band, without ever meeting.  After moving to Los Angeles at age 23, he composed, arranged, and performed alongside Yanni for more than six years, performing in-concert with a number of notable symphony orchestras, touring throughout the U.S. and abroad as Yanni gained worldwide fame. His first show was at the Starplex in Dallas with the Dallas Symphony Orchestra filming a video project. "It was a real trial by fire for me", said Joseph. "First show + 10,000 people + TV cameras equals NERVOUS." He told Jane Fredericksen of the St. Croix Valley Press that "It was a big jump, you don't really realize it at the time, but there's no in-between -- going from playing nightclubs to arenas." Some of these early tours included the Reflections of Passion, Revolution in Sound, Dare to Dream, Yanni Live, The Symphony Concerts 1993 and 1994 concert tours, as well as a performance in Germany that was broadcast throughout Europe and seen by 30 to 40 million viewers. Joseph appears on the 1994 multi-platinum album and video, Live at the Acropolis. He recounts, "When I reflect back over the years, one of the high points that stand out include performing at the Acropolis with Yanni. Imagine all these different cultures coming together with the challenges of language, equipment, travel, and weather problems. I still picture the police running their dogs through the dressing rooms to sniff out any bomb possibilities right before the show. People still come up to me and comment how that show has affected their lives."  In the band, Joseph covered a lot of the keyboard parts that Yanni could not for lack of hands in the shows. He assisted with the task of managing the 30 or more synthesizers onstage, and helped layer with the orchestra to create a "full-bodied, live-effect sound". He did have to adjust some parts that did not work well in a live situation and worked extensively on programming sounds for all keyboardists. Joseph said that "Yanni gave us musicians a great deal of freedom to expand the music as well. If you listen to the original recordings he did and what we ended up with in our live recordings, you can really hear the musician's input." He readily credits Yanni's role in his professional development, and for five years of irreplaceable experiences and memories.  Between tours, Joseph worked extensively in recording studios on music ranging from rock and pop to rhythm and blues and orchestration with numerous artists from RCA, Epic, Warner Brothers, and Polygram Records, in addition to performing in an elaborate national keyboard show tour with various musicians. In 2003, he returned for the 60-city Ethnicity tour.

Question:
Frank Vincent Zappa (December 21, 1940 - December 4, 1993) was an American musician, composer, activist and filmmaker. His work is characterized by nonconformity, free-form improvisation, sound experiments, musical virtuosity, and satire of American culture. In a career spanning more than 30 years, Zappa composed rock, pop, jazz, jazz fusion, orchestral and musique concrete works, and produced almost all of the 60-plus albums that he released with his band the Mothers of Invention and as a solo artist. Zappa also directed feature-length films and music videos, and designed album covers.
Zappa and the Mothers of Invention returned to Los Angeles in mid-1968, and the Zappas moved into a house on Laurel Canyon Boulevard, only to move again to one on Woodrow Wilson Drive. This was Zappa's home for the rest of his life. Despite being a success with fans in Europe, the Mothers of Invention were not faring well financially. Their first records were vocally oriented, but Zappa wrote more instrumental jazz and classical oriented music for the band's concerts, which confused audiences. Zappa felt that audiences failed to appreciate his "electrical chamber music".  In 1969 there were nine band members and Zappa was supporting the group himself from his publishing royalties whether they played or not. 1969 was also the year Zappa, fed up with MGM Records' interference, left them for Warner Bros. Records' Reprise subsidiary where Zappa/Mothers recordings would bear the Bizarre Records imprint.  In late 1969, Zappa broke up the band. He often cited the financial strain as the main reason, but also commented on the band members' lack of sufficient effort. Many band members were bitter about Zappa's decision, and some took it as a sign of Zappa's concern for perfection at the expense of human feeling. Others were irritated by 'his autocratic ways', exemplified by Zappa's never staying at the same hotel as the band members. Several members played for Zappa in years to come. Remaining recordings with the band from this period were collected on Weasels Ripped My Flesh and Burnt Weeny Sandwich (both released in 1970).  After he disbanded the Mothers of Invention, Zappa released the acclaimed solo album Hot Rats (1969). It features, for the first time on record, Zappa playing extended guitar solos and contains one of his most enduring compositions, "Peaches en Regalia", which reappeared several times on future recordings. He was backed by jazz, blues and R&B session players including violinist Don "Sugarcane" Harris, drummers John Guerin and Paul Humphrey, multi-instrumentalist and previous member of the Mothers of Invention Ian Underwood, and multi-instrumentalist Shuggie Otis on bass, along with a guest appearance by Captain Beefheart (providing vocals to the only non-instrumental track, "Willie the Pimp"). It became a popular album in England, and had a major influence on the development of the jazz-rock fusion genre.
