Background: The Electric Light Orchestra (ELO) are an English rock band formed in Birmingham in 1970, by songwriters/multi-instrumentalists Jeff Lynne and Roy Wood with drummer Bev Bevan. Their music is characterised by a fusion of Beatlesque pop, classical arrangements, and futuristic iconography. After Wood's departure in 1972, Lynne became the band's leader, arranging and producing every album while writing virtually all of their original material. For their initial tenure, Lynne, Bevan and keyboardist Richard Tandy were the group's only consistent members.
Context: The success of the Children in Need was followed by much support from BBC Radio 2's DJ Chris Evans, who asked his listeners if they wanted ELO to perform. The 50,000 tickets for the resulting BBC Radio 2's "Festival in a Day" in Hyde Park on 14 September 2014 sold out in 15 minutes. Billed as "Jeff Lynne's ELO", Lynne and Tandy were backed by the Take That/Gary Barlow band from the Children in Need concert, led by Mike Stevens  and the BBC Concert Orchestra. The moniker came out from Lynne as a response to ELO tribute and imitation bands, (ELO Part II, the Orchestra, OrKestra and the Music of ELO) who repeatedly used ELO for promoting their own tours. Chereene Allen was the lead violinist for the band. The development of modern digital processing added a smoother finish to the work, which led Lynne to reconsider his preference for studio work, hinting at a UK tour in 2015.  On 8 February 2015, Jeff Lynne's ELO played at the Grammy Awards for the first time. They performed a medley of "Evil Woman" and "Mr. Blue Sky" with Ed Sheeran, who introduced them as "A man and a band who I love".  On 10 September 2015, it was announced that a new ELO album would be released. The album was to be under the moniker of Jeff Lynne's ELO, with the band signed to Columbia Records. Alone in the Universe was released on 13 November 2015. The album was ELO's first album of new material in nearly 15 years. The first track, and single, "When I Was a Boy" was made available for streaming on the same day and a music video for the song was also released. A small promotional tour followed the album's release which saw ELO perform a full concert for BBC Radio 2 along with ELO's first two shows in the United States in 30 years, both which sold out very quickly. ELO also made rare US television appearances on The Tonight Show Starring Jimmy Fallon, Jimmy Kimmel Live and CBS This Morning. Lynne was joined by Traveling Wilbury's photographer Nick J (NJ Latham) for a 19-date European tour that was announced for 2016, with the band playing the Pyramid Stage at Glastonbury Festival on 26 June 2016.  In 2017 they played their "Alone in the Universe" tour. In 2017 they played at the Rock and Roll Hall of Fame during the 32nd Annual Induction Ceremony.
