Per Nørgård (pronounced [ˈpʰeɐ̯ ˈnɶɐ̯ɡ̊ɒːˀ]) (born July 13, 1932) is a Danish composer.

Nørgård was born in Gentofte, Denmark. He studied with Vagn Holmboe at the Royal Danish Academy of Music in Copenhagen, and subsequently with Nadia Boulanger in Paris. To begin with, he was strongly influenced by the Nordic styles of Jean Sibelius, Carl Nielsen and Vagn Holmboe. In the 1960s, Nørgård began exploring the modernist techniques of central Europe, eventually developing a serial compositional system based on the "infinity series" (Nørgård 1975), which he used in his Voyage into the Golden Screen, the Second and Third Symphonies, I Ching, and other works of the late 1960s and 70s (Mortensen [n.d.]). Later he became interested in the Swiss artist Adolf Wölfli, who inspired many of Nørgård's works (Anon [n.d.]), including the 4th symphony, the opera Det Guddommelige Tivoli and Papalagi for solo guitar.

Nørgård has composed works in all major genres: six operas, two ballets, seven symphonies and other pieces for orchestra, several concertos, choral and vocal works, an enormous number of chamber works (among them ten string quartets) and several solo instrumental works. These include a number of works for the guitar, mostly written for the Danish guitarist Erling Møldrup: In Memory Of... (1978), Papalagi (1981), a series of suites called Tales from a Hand (1985–2001), Early Morn (1997–98) and Rondino Amorino (1999). One of his most important works for percussion solo is I Ching (1982) for the Danish percussionist Gert Mortensen. He has also composed music for several films, including The Red Cloak (1966), Babette's Feast (1987), and Hamlet, Prince of Denmark (1993).

Leif Segerstam (born 2 March 1944 in Vaasa) is a Finnish conductor and composer.

He studied violin, piano and conducting at the Sibelius Academy in Helsinki and conducting at the Juilliard School in New York with Jean Morel.

Segerstam served as chief conductor of the Helsinki Philharmonic Orchestra from 1995 to 2007, and now holds the title of Chief Conductor Emeritus with the orchestra. He has held positions with numerous other orchestras, including the Danish National Radio Symphony and the Austrian Radio Symphony, and has guest-conducted many orchestras throughout the world including the Chicago Symphony, the Los Angeles Philharmonic, the Toronto Symphony and the Brazilian OSESP - the Symphony Orchestra of the State of São Paulo. He is also the professor of conducting at the Sibelius Academy in Helsinki. His students include Susanna Mälkki, Mikk Murdvee, Sasha Mäkilä and Markku Laakso.^{[citation needed]}

He is widely known through his recorded discography, which includes the complete symphonies of Sibelius, Nielsen, and Mahler, as well as many works by contemporary composers such as the Finnish composer Einojuhani Rautavaara and the American composers John Corigliano and Christopher Rouse.

John Gunnar Rafael Storgårds (born 20 October 1963) is a Finnish violinist and conductor.

Storgårds studied violin with Esther Raitio and Jouko Ignatius at the Sibelius Academy in Helsinki, and continued his violin studies with Chaim Taub in Israel. He was a founding member of the Avanti! Chamber Orchestra. After experience leading orchestras from the front desk of the violin section, his interest in conducting increased after an invitation to conduct the Helsinki University Symphony Orchestra. He subsequently returned to the Sibelius Academy from 1993-1997 to study conducting with Jorma Panula and Eri Klas.

In 1996, Storgårds became Artistic Director of the Chamber Orchestra of Lapland. With the Helsinki Philharmonic Orchestra, he became Principal Guest Conductor in 2003 and subsequently Chief Conductor in autumn 2008, for an initial contract of 4 years. His Helsinki contract has since been extended to 2014. From 2006 to 2009, Storgårds was Chief Conductor of the Tampere Philharmonic Orchestra. Storgårds has held the Artistic Directorships of many summer festivals, most recently of the Korsholm Music Festival between 2004–2006, and Avanti's! Summer Sounds Festival. Outside of Finland, in March 2011, Storgårds was appointed principal guest conductor of the BBC Philharmonic, effective January 2012, succeeding Vassily Sinaisky.
