Context paragraphs:
M Lamar: M Lamar (born May 29) is a New York City-based composer, musician, performer, multimedia artist, and counter tenor.  The New York Times describes his exhibit 'Negrogothic' as "a bracing alternative to the dispiriting traffic in blandly competent art clogging the New York gallery system these days, M. Lamar plumbs the depths of all-American trauma with visionary verve."  Hilton Als wrote in The New Yorker of M. Lamar "he deconstructs the persona of the diva even as he wraps himself in divalike hauteur."

Omeros: Omeros is an epic poem by Caribbean writer Derek Walcott, first published in 1990.  The work is divided into seven "books" containing a total of sixty-four chapters.  Many critics view "Omeros" as Walcott's "major achievement."  Soon after its publication in 1990, it received praise from publications like "The Washington Post" and "The New York Times Book Review", the latter of which chose the book as one of its "Best Books of 1990" and called it "one of Mr. Walcott's finest poetic works."  The book also won the WH Smith Literary Award in 1991.  In 1992, Walcott was also awarded the Nobel Prize for Literature, and the Nobel committee member who presented the award, Professor Kjell Espmark, singled out Walcott's most recent achievement at the time, "Omeros", recognizing the book as a "major work".  Walcott painted the cover for the book, which depicts some of his main characters at sea together in a boat.  In 2004, the critic Hilton Als of "The New Yorker" called the book "Walcott's masterpiece" and characterized the poem as "the perfect marriage of Walcott’s classicism and his nativism".
