The Orchestra of the Swan is the resident chamber orchestra at Birmingham Town Hall, where weekly recitals have also been given by the City Organist since 1834. The Birmingham Triennial Music Festivals took place from 1784 to 1912. Music was specially composed, conducted or performed by Mendelssohn, Gounod, Sullivan, Dvořák, Bantock and Edward Elgar, who wrote four of his most famous choral pieces for Birmingham. Elgar's "The Dream of Gerontius" had its début performance there in 1900. Composers born in the city include Albert William Ketèlbey and Andrew Glover. Jazz has been popular in the city since the 1920s, and there are many regular festivals such as the Harmonic Festival, the Mostly Jazz Festival and the annual International Jazz Festival. Birmingham's other city-centre music venues include Arena Birmingham (previously known as the National Indoor Arena and the Barclaycard Arena), which was opened in 1991, O2 Academy on Bristol Street, which opened in September 2009 replacing the O2 Academy in Dale End, the CBSO Centre, opened in 1997, HMV Institute in Digbeth and the Bradshaw Hall at the Royal Birmingham Conservatoire. During the 1960s, Birmingham was the home of a music scene comparable to that of Liverpool. It was "a seething cauldron of musical activity", and the international success of groups such as The Move, The Spencer Davis Group, The Moody Blues, Traffic and the Electric Light Orchestra had a collective influence that stretched into the 1970s and beyond. The city was a centre for early heavy metal music, with pioneering metal bands from the late 1960s and 1970s such as Black Sabbath, Judas Priest, and half of Led Zeppelin having come from Birmingham. The next decade saw the influential metal bands Napalm Death and Godflesh emerge from the city. Birmingham was the birthplace of modern bhangra in the 1960s, and by the 1980s had established itself as the global centre of bhangra culture, which has grown into a global phenomenon embraced by members of the Indian diaspora worldwide from Los Angeles to Singapore. The 1970s also saw the rise of reggae and ska in the city with such bands as Steel Pulse, UB40, Musical Youth, The Beat and Beshara, expounding racial unity with politically leftist lyrics and multiracial line-ups, mirroring social currents in Birmingham at that time. Other popular bands from Birmingham include Duran Duran, Fine Young Cannibals, Felt, Broadcast, Ocean Colour Scene, The Streets, The Twang, King Adora, Dexys Midnight Runners, Hosen Brass and Magnum.
