Artur Uritamm (Tõstamaa, September 9, 1901 – Pärnu, July 8, 1982) was an Estonian classical composer, organist and pedagogue.
An unfinished symphony is a fragment of a symphony, by a particular composer, that musicians and academics consider incomplete or unfinished for various reasons.
 The archetypal unfinished symphony is Franz Schubert's Symphony No. 8 (sometimes called "Schubert's Unfinished Symphony"), written in 1822, six years before his death.
 It features two fully orchestrated movements.
 While it seems clear from sketches that Schubert set out to create a traditional four-movement symphony, this has been the subject of endless debate.
 Schubert wrote the symphony for the Graz Musical Society, and gave the manuscript to his friend Anselm Hüttenbrenner, in his capacity as its representative.
 However, Hüttenbrenner did not show the score to the society at that time, nor did he reveal the existence of the manuscript after Schubert died in 1828, but kept it a secret for another 37 years.
 In 1865, when he was 76 (three years before his death), Hüttenbrenner finally showed it to the conductor Johann von Herbeck, who conducted the extant two movements on 17 December 1865 in Vienna, adding the last movement of Schubert's third symphony as the finale.
 Music historians and scholars then toiled to "prove" the composition was complete in its two-movement form, and indeed, in that form it became one of the most popular pieces in the late 19th century classical music repertoire, and remains one of Schubert's most popular compositions.
Fred Stone (sometimes given as Freddie Stone) (9 September 1935 – 10 December 1986) was a Canadian flugelhornist, trumpeter, pianist, composer, writer, and music educator.
 He worked as a soloist within both the classical and jazz repertoires from the 1950s through the early 1970s, notably appearing in concerts with the Duke Ellington Orchestra, the Toronto Symphony Orchestra, the Winnipeg Symphony Orchestra, the Detroit Symphony Orchestra, the Cleveland Orchestra, the Buffalo Philharmonic Orchestra, the Ottawa Symphony Orchestra, and the San Diego Symphony.
 Between 1971 and 1983 he mainly focused on his work as a composer and teacher, making only periodic public performances.
 In 1984 he resumed actively performing when he formed "Freddie's Band", a jazz ensemble in residence at The Music Gallery in Toronto.
 He performed with this group up until his death two years later.

Artur Lemba (24 September 1885, Tallinn – 21 November 1963, Tallinn) was an Estonian composer and piano teacher, and one of the most important figures in Estonian classical music.

 It was premiered on November 2, 2005 at Brooklyn Academy of Music by Bruckner Orchester Linz conducted by Dennis Russell Davies.
 The symphony is in three movements and features extended solo writing.
 Critic Allan Kozinn described the symphony's chromaticism as more extreme, more fluid, and its themes and textures as continually changing, morphing without repetition, and praised the symphony's "unpredictable orchestration", pointing out the "beautiful flute and harp variation in the melancholy second movement".
 Alex Ross remarked that "against all odds, this work succeeds in adding something certifiably new to the overstuffed annals of the classical symphony.
 (...) The musical material is cut from familiar fabric, but it’s striking that the composer forgoes the expected bustling conclusion and instead delves into a mood of deepening twilight and unending night."
Symphony No. 4, "Los Angeles", is the fourth symphony by Estonian composer Arvo Pärt.
