Toivo Kuula: Toivo Timoteus Kuula (7 July 1883, Vaasa – 18 May 1918, Viipuri) was a Finnish composer and conductor of the late-Romantic and early-modern periods, who emerged in the wake of Jean Sibelius, under whom he studied privately from 1906 to 1908.  The core of Kuula's oeuvre are his many works for voice and orchestra, in particular the "Stabat mater" (1914–18; completed by Madetoja), "The Sea-Bathing Maidens" (1910), "Son of a Slave" (1910), and "The Maiden and the Boyar's Son" (1912).

Leevi Madetoja: Leevi Antti Madetoja (] ; 17 February 1887, Oulu – 6 October 1947, Helsinki) was a Finnish composer, music critic, conductor, and teacher of the late-Romantic and early-modern periods; he is generally considered to be among the most significant Finnish composers to emerge after Jean Sibelius, under whom he studied privately from 1908–10.  The core of Madetoja's oeuvre consists of a set of three symphonies (1916, 1918, and 1926), arguably the finest early-twentieth century additions to the Finnish canon of any composer, Sibelius excepted.  As central to Madetoja's legacy is his opera, "The Ostrobothnians" (1924), dubbed Finland's "national opera" following its successful premiere and, even today, a stalwart of its repertoire.  Madetoja's other notable works include an "Elegia" for strings (1909); "The Garden of Death" (1918–21), a three-movement suite for solo piano; the "Japanisme" ballet-pantomime, "Okon Fuoko" (1927); and, a second opera, "Juha" (1935).

Symphonic Fantasies: Symphonic Fantasies: Music from Square Enix was an award-winning symphonic tribute concert held in Cologne, Germany on September 12, 2009 at the Cologne Philharmonic Hall featuring video game music from Japanese game developer Square Enix.  The concert featured symphonic movements based on the "Kingdom Hearts" series, "Secret of Mana", the "Chrono" series, and the "Final Fantasy" series.  The concert was produced and directed by Thomas Böcker, with arrangements provided by Finnish composer and musician Jonne Valtonen with assistance by Roger Wanamo.  Due to overwhelming demand, a second concert was necessitated at the König-Pilsener-Arena in Oberhausen, on September 11, 2009.  The concert was performed by the WDR Radio Orchestra Cologne and the WDR Radio Choir Cologne under conduction from Arnie Roth, with guest performers Rony Barrak and Benyamin Nuss joining the orchestra.  "Symphonic Fantasies" was broadcast over radio on the WDR4 station and streamed live video online.

Elegia (Madetoja): Elegia (In English: Elegy; occasionally with the Finnish subtitle "Suru ", or "Sadness"), Op.  4/1, is a composition for string orchestra by the Finnish composer Leevi Madetoja, who wrote the piece in 1909 during his student years.  On 10 January 1910, Robert Kajanus, chief conductor of the Helsinki Orchestral Society, premiered the "Elegia" to great acclaim, with the piece described as the "first master work" of a budding "natural orchestral composer".  Madetoja subsequently designated the "Elegia" as the first number in his four-movement "Sinfoninen sarja" ("Symphonic Suite"), Op. 4, which the Helsinki Orchestral Society performed in its entirety under the composer's baton on 26 September 1910.  The suite's three other numbers are virtually unknown, and the "Elegia" typically is performed as a stand-alone concert piece.  Stylistically reminiscent of Tchaikovsky, it is, to date, Madetoja's most recorded and well-known orchestral composition, as well as the most enduringly popular of his many miniatures.

March law (Anglo-Scottish border): March law (Anglo-Scottish border) (or Marcher law, or laws and customs of the marches) was a system of customary international law dealing with cross-border dispute settlement, operating during the medieval and early-modern periods in the area of the Anglo-Scottish border or Anglo-Scottish marches - the word "march" being the Old English form of the Old French word "marche" meaning "boundary" (the Anglo-Welsh border and the Anglo-Irish marches had their own versions of "the Law of the Marches").  They were " essentially a set of regulations for the prosecution of offences committed by the inhabitants of one country inside the territory of the other, and for the recovery of property stolen or lent across their common border."
