[EX Q]: Context: A record producer or music producer oversees and manages the sound recording and production of a band or performer's music, which may range from recording one song to recording a lengthy concept album. A producer has many roles during the recording process. The roles of a producer vary.

It is the capital of the "Landkreis" or county Lindau, Bavaria, and located near the borders of Austria (Vorarlberg) and Switzerland (St. Gallen and Thurgau).

Unlike later albums by the group , it was released by the ECM label and produced by Manfred Eicher . The album was not released in the USA until 1975 . The record is often considered one of the classic albums in electric jazz . At this stage Corea 's approach to jazz fusion was very different compared to other early fusion artists . Adventurous electric piano solos are backed with South American oriented rhythms of drummer Airto Moreira and the vocals and percussion of his wife Flora Purim . Stanley Clarke is the bassist of the group ( playing electric bass on A-side and double bass on B - side ) and Joe Farrell plays flute and saxophone . This first line - up of Return to Forever consists of musicians ( excluding Joe Farrell and Flora Purim ) that were also playing on Stan Getz 's album Captain Marvel that was released in the same year . The first track can be divided into five parts . There are three short parts in which Corea plays simple , haunting melodies with Purim doubling them with her voice . Between these three parts there are two longer parts in which the whole band plays . These main parts are both based on their own riffs . Farrell plays a flute solo over the first main part and Corea plays solo over the second . Moreira 's drum pattern gives the composition an airy feeling of its own . Purim sings along with riffs , screaming a bit towards the end . The second track , `` Crystal Silence '' , is Corea 's song . The track is played just by Corea and Farrell with some soft percussion in the background . Farrell performs a long saxophone solo . Third track , `` What Game Shall We Play Today ? '' , is another of Corea 's songs . It has a very affectionate melody and Purim singing vocals . Farrell is now playing the flute . Corea and Farrell give short solos between the second and the third verse . The band would return to this song during the Light as a Feather sessions later in 1972 , when they made four attempts with it ; though the song did not make it to the album , all the takes appeared on the expanded edition of Light as a Feather . The B - side of the album has only one track which consists of three different pieces of music . Probably they have been recorded without breaks and this is the main reason why they are not separated on three individual tracks ; the bass lines skilfully link them together as well . The first seven minutes of the track consist of an improvised introduction featuring Corea , Farrell and Clarke , slow - paced and feeling akin to a Chinese landscape painting . As this section closes the piece moves into `` Sometime Ago '' . It is a Latin flavored song with Purim 's vocals and Farrell soloing on flute . After that song Farrell switches to soprano saxophone and the band plays `` La Fiesta '' , one of Corea 's jazz standards . Corea has written that most Spanish songs deal with matters such as misery or torture but `` La Fiesta '' , however , is about celebration . The song is an instrumental piece that relies on flamenco modes ., Jazz fusion (also known as jazz-rock) is a musical genre that developed in the late 1960s when musicians combined aspects of jazz harmony and improvisation with styles such as funk, rock, rhythm and blues, and Latin jazz. During this time many jazz musicians began experimenting with electric instruments and amplified sound for the first time, as well as electronic effects and synthesizers. Many of the developments during the late 1960s and early 1970s have since become established elements of jazz fusion musical practice., Germany, officially the Federal Republic of Germany, is a federal parliamentary republic in central-western Europe.

Germany's capital and largest metropolis is Berlin. Other major cities include Hamburg, Munich, Cologne, Frankfurt, Stuttgart and Düsseldorf., Funk is a music genre that originated in the mid- 1960s when African American musicians created a rhythmic, danceable new form of music through a mixture of soul music, jazz, and rhythm and blues (R&B). Funk de-emphasizes melody and chord progressions used in other related genres and brings a strong rhythmic groove of a bass line played by an electric bassist and a drum part played by a drummer to the foreground. Funk songs are often based on an extended vamp on a single chord, distinguishing them from R&B and soul songs, which are built on complex chord progressions. Funk uses the same richly-colored extended chords found in bebop jazz, such as minor chords with added sevenths and elevenths, or dominant seventh chords with altered ninths., Latin jazz is a genre of jazz with Latin American rhythms. Although musicians continually expand its parameters, the term "Latin jazz" is generally understood to have a more specific meaning than simply "jazz from Latin America". Some Latin jazz typically employs rhythms that either have a direct analog in Africa, or exhibit an African influence.
The two main categories of Latin jazz are:, ECM (Edition of Contemporary Music) is an independent record label founded by Manfred Eicher in Munich in 1969. While ECM is best known for jazz music, the label has released a variety of recordings, and ECM's artists often refuse to acknowledge boundaries between genres. ECM's motto is "the Most Beautiful Sound Next to Silence", according to a 1971 review of ECM releases in "CODA", a Canadian jazz magazine., Rhythm and blues, often abbreviated as R&B or RnB, is a genre of popular African-American music that originated in the 1940s. The term was originally used by record companies to describe recordings marketed predominantly to urban African Americans, at a time when "urbane, rocking, jazz based music with a heavy, insistent beat" was becoming more popular.
In the commercial rhythm and blues music typical of the 1950s through the 1970s, the bands usually consisted of piano, one or two guitars, bass, drums, saxophone, and sometimes background vocalists. R&B lyrical themes often encapsulate the African-American experience of pain and the quest for freedom and joy. Lyrics focus heavily on the themes of triumphs and failures in terms of relationships, freedom, economics, aspirations, and sex., Subject: return to forever , Relation: record_label, Options: (A) album (B) ecm records (C) europe (D) funk (E) island (F) label (G) latin (H) metropolis (I) record (J) record label
