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.
For the next six years, Harvest and Epic/Legacy reissued ELO's back catalogue. Included amongst the remastered album tracks were unreleased songs and outtakes, including two new singles. The first was "Surrender" which registered on the lower end of the UK Singles Chart at number 81, some 30 years after it was written in 1976. The other single was "Latitude 88 North".  On 9 August 2010, Eagle Rock Entertainment released Live - The Early Years in the UK as a DVD compilation that included Fusion - Live in London (1976) along with never before released live performances at Brunel University (1973) and on a German TV show Rockpalast (1974). The US had a slightly edited release on 24 August 2010. The Essential Electric Light Orchestra artwork was re-jigged to feature two different covers. The US and Australian releases shared one design, while the rest of the world featured the other for a new double album release in October 2011.  Mr. Blue Sky: The Very Best of Electric Light Orchestra was released on 8 October 2012. It is an album of new recordings of ELO's greatest hits by Lynne; along with a new song "Point of No Return", released to coincide with Lynne's second solo album release Long Wave. These new 2012 albums contained advertisement cards, announcing the re-release of expanded and remastered versions of both the 2001 album Zoom and Lynne's debut solo album Armchair Theatre, originally released in 1990. Both albums were re-released in April 2013 with various bonus tracks. Also released was the live album, Electric Light Orchestra Live, showcasing songs from the Zoom tour. All three releases also featured new studio recordings as bonus tracks.  Lynne and Tandy reunited again on 12 November 2013 to perform, under the name Jeff Lynne and Friends, "Livin' Thing" and "Mr Blue Sky" at the Children in Need Rocks concert at Hammersmith Eventim Apollo, London. The backing orchestra was the BBC Concert Orchestra, with Chereene Allen on lead violin.

How many miniature reunions did they have?

Roberto Mangabeira Unger (; born 24 March 1947) is a philosopher and politician. He has developed his views and positions across many fields, including social, political, and economic theory. In legal theory, he is best known by his work in the 1970s and 80s while at Harvard Law School as part of the Critical Legal Studies movement, which is held to have helped disrupt the methodological consensus in American law schools. His political activity helped the transition to democracy in Brazil in the aftermath of the military regime, and culminated with his appointment as Brazil's Minister of Strategic Affairs in 2007 and again in 2015.
Unger's critique of economics begins with the identification of a key moment in economic history, when the analysis of production and exchange turned away from social theory and engaged in a quest for scientific objectivity. In Unger's analysis, classical economics focused on the causal relations among social activities, which were connected with the production and distribution of wealth. Classical economists asked questions about the true basis of value, activities that contributed to national wealth, systems of rights, or about the forms of government under which people grow rich. In the late-nineteenth century, in response to attacks from socialist ideas and debates about how society works, and as a means to escape the conundrums of value theory and to answer how values could become prices, marginalist economics arose. This movement in economics disengaged economics from prescriptive and normative commitments to withdraw the study of economies from debates about how society worked and what kind of society we wanted to live in. For Unger, this moment in the history of economics robbed it of any analytical or practical value.  Unger's critique of Marginalism begins with Walras' equilibrium theory, which attempted to achieve a certainty of economic analysis by putting aside normative controversies of social organization. Unger finds three weaknesses that crippled the theory: foremost, the theory claimed that equilibrium would be spontaneously generated in a market economy. In reality, a self-adjusting equilibrium fails to occur. Second, the theory puts forth a determinate image of the market. Historically, however, the market has been shown to be indeterminate with different market arrangements. Third, the polemical use of efficiency fails to account for the differences of distribution among individuals, classes, and generations.  The consequences of the marginalist movement were profound for the study of economics, Unger says. The most immediate problem is that under this generalizing tendency of economics, there is no means by which to incorporate empirical evidence and thus to re-imagine the world and develop new theories and new directions. In this way, the discipline is always self-referential and theoretical. Furthermore, the lack of a normative view of the world curtails the ability to propose anything more than a policy prescription, which by definition always assumes a given context. The discipline can only rationalize the world and support a status quo. Lastly, Unger finds that this turn in economics ended up universalizing debates in macroeconomics and leaving the discipline without any historical perspective. A consequence, for example, was that Keynes' solution to a particular historical crisis was turned into a general theory when it should only be understood as a response to a particular situation.
