Question: Viktor Selyavin is best known for his interpretation of Lensky in  an opera composed by who?
Context: American Indian opera is a subgenre of American music.  It began with composer Gertrude Bonnin (1876-1938), also known as Zitkala-Sa ("Red Bird" in Lakota).  Bonnin's own Yankton Sioux heritage informed both her libretto and music for her opera "The Sun Dance", a grand opera composed with Mormon musician William F. Hanson. Viktor Alekseyevich Selyavin Russian: Виктор Алексеевич Селявин (1875–1945) was a leading tenor of the Odessa Opera and Ballet Theater.  He is often referred to as Odessa's Sobinov, a reference to Leonid Sobinov, one of the best known Russian tenors of the first half of the twentieth century.  His repertoire included the tenor roles of most major operas, but he is best known for his interpretation of Lensky in "Eugene Onegin".  He also performed in chamber music, being especially fond of Mikhail Glinka's and Pyotr Ilyich Tchaikovsky's romances. Eugene Onegin (Russian: Евгений Онегин , "Yevgény Onégin"), Op.  24, is an opera ("lyrical scenes") in 3 acts (7 scenes), composed by Pyotr Ilyich Tchaikovsky.  The libretto, organised by the composer himself, very closely follows certain passages in Alexander Pushkin's novel in verse, retaining much of his poetry.  Tchaikovsky's friend Konstantin Shilovsky contributed M. Triquet's verses in Act 2, Scene 1, while Tchaikovsky himself arranged the text for Lensky's arioso in Act 1, Scene 1, and almost all of Prince Gremin's aria in Act 3, Scene 1. The Inman Diaries is an opera composed by Thomas Oboe Lee with a libretto by Jesse J. Martin.  This portrayal of Arthur Crew Inman's life, as seen through his own writings was originally adapted from 'Camera Obscura', a play by Lorenzo DeStefano (http://www.cameraobscuraplay.com) and "The Inman Diary: A Public and Private Confession", edited by Professor Daniel Aaron.  From 1919 until he committed suicide in 1963, he created his 155 volume diary which contained over 17 million words, making it one of the longest recorded diaries in the English language.  He was an obsessive recluse who was committed to having his diaries published to establish his immortality.  He would pay people to “talk” to him so that he could make a record of their stories.  He was particularly interested in young women and was known to be sexually involved with some of these “talkers”.  The opera is based on a 44-year period of his life, adapted so that the decades are condensed and time loses its relevancy.
