The John Alldis Choir 是一个耐用的英国合唱团，尤其以其现代音乐表演而着称。约翰·阿尔迪斯是剑桥大学的一名音乐系学生，他获得了剑桥国王学院合唱学者的奖学金，他的合唱大师是鲍里斯·奥德。合唱学者是男学生，他们通过了一场严格的竞争性试镜，在着名的国王学院合唱团中演唱。通过考试的人可以获得剑桥教育，以换取每日国王学院礼拜堂的歌唱服务。毕业后，他于1962年成立了John Alldis合唱团，最初包括16位专业歌手。

1962年，他们在伦敦举办了一场音乐会，其中包括亚历山大·戈尔（Alexander Goehr）的“咒语小颂歌”（A Little Cantata of Proverbs）的全球首演。在同一年，他们还首演了马尔科姆·威廉姆森的“声音交响曲”，这部作品需要演奏大师的演唱和非常详细的合奏。这些表演非常成功，合唱变得非常需要。

在1966年之前，伦敦交响乐团没有永久合唱团。作为一个财务上不确定的组织，直到50年代后期重组，乐团聘请一个或另一个可用的合唱团在需要时与其合唱，有时以伦敦交响乐合唱团的名义。 1966年，LSO决定组建一个永久合唱团，并聘请Alldis作为其第一位音乐总监。 1969年，当他在伦敦爱乐合唱团担任类似职务时，他仍然留在这个合唱团。 1972年，他还担任丹麦国家广播合唱团的领导。

与此同时，他维持着约翰·阿尔迪斯合唱团的组织。 1967年，合唱团参加了由勃朗文斯基的安魂曲颂歌演奏的第一部欧洲演出，由Pierre Boulez指挥并由Alldis编写。从1968年到大约20世纪70年代，他们活跃于录音室，主要参与歌剧录音，尤其是RCA和Decca（伦敦）唱片。对于这些工作室日期，Alldis将按照制作人和会议指挥的要求雇用额外的歌手。

The John Alldis Choir was a durable British choral ensemble especially notable for its performances of modern music. John Alldis was a music student at Cambridge who won a scholarship as a choral scholar to King's College, Cambridge, where his chorus master was Boris Ord. Choral scholars are male students who has passed a rigorous competitive audition to sing in the famous Chorus of King's College. Those who pass receive a Cambridge education in return for singing at the daily King's College Chapel services. After his graduation he formed the John Alldis Choir in 1962, which originally included 16 professional singers.

They made their concert debut in London in 1962 in a program that included the world premiere of Alexander Goehr's A Little Cantata of Proverbs; in the same year they also premiered Malcolm Williamson's Symphony for Voices, a work requiring virtuoso singing and exceptionally detailed ensemble blend. These performances were highly successful, and the chorus became much in demand.

Prior to 1966, the London Symphony Orchestra had no permanent choral organization. A financially uncertain organization until its reorganization in the late '50s, the orchestra engaged one or another available choir to sing with it when needed, sometimes under the name London Symphony Chorus. In 1966, the LSO decided to form a permanent choral group, and engaged Alldis to assemble it as its first music director. He remained with this chorus through 1969, when he took a similar position with the London Philharmonic Choir. In 1972, he also took on the leadership of the Danish State Radio Chorus.

Meanwhile, he maintained the organization of the John Alldis Choir. In 1967, the choir participated in the first European performance of Stravinsky's Requiem Canticles, conducted by Pierre Boulez and prepared by Alldis. From 1968 through roughly the 1970s, they were active in recording studios, mostly participating in opera recordings, particularly with RCA and Decca (London) records. For these studio dates, Alldis would hire additional singers as required by the producer and conductor of the sessions.
