Gray's Anatomy is an English-language human anatomy textbook originally written by Henry Gray. Earlier editions were called Anatomy: Descriptive and Surgical, but the book's name is commonly shortened to, and later editions are titled, Gray's Anatomy. The book is widely regarded as an extremely influential work on the subject, and has continued to be revised and republished from its initial publication in 1858 to the present day. The 40th (and 150th-year anniversary) edition of the book was published in 2008.

Spalding Rockwell Gray (June 5, 1941 – January 11, 2004) was an American actor, playwright, screenwriter, performance artist and monologuist. He was primarily known for his "trenchant, personal narratives delivered on sparse, unadorned sets with a dry, WASP, quiet mania." Gray achieved celebrity status for his monologue Swimming to Cambodia, which was adapted into a film in 1987 by Jonathan Demme.

He began his career in regional theatre, moved to New York in 1967 and three years later joined Richard Schechner's experimental troupe, the Performance Group. He co-founded the Wooster Group ensemble in 1975. He died in New York City of an apparent suicide in 2004. A documentary film about his life, entitled And Everything Is Going Fine, was released in 2010 and was directed by Steven Soderbergh.

Gray was born in Providence, Rhode Island, to Rockwell Gray, Sr., the treasurer of Brown & Sharpe, and Margaret Elizabeth "Betty" Horton, a homemaker. He was the middle-born of three sons: Rockwell, Jr., Spalding and Channing. He was raised in the Christian Scientist faith and grew up in Barrington, Rhode Island, spending summers at his grandmother's house in Newport.

Sonata Arctica is a Finnish power metal band from the town of Kemi, originally assembled in 1995. Their later works (most notably The Days of Grays, Unia and a few tracks on Reckoning Night and Winterheart's Guild) contain several elements typical of progressive metal.

The band was founded by Marko Paasikoski, Jani Liimatainen and Tommy Portimo in Kemi at the end of 1995 (Tony Kakko and Pentti Peura joined in early 1996). Originally named Tricky Beans, they played hard rock rather than the power metal with which they grew to fame. During their early career, they recorded three demos which were never sent to any recording label — Friend 'till the End, Agre Pamppers and PeaceMaker.

In 1997 the band changed their name to Tricky Means, and from that point until 1999 their style was thoroughly worked upon and ultimately was drastically changed, acquiring strong emphasis on the keyboard melodies and relying on an easily distinguishable rhythm line maintained both by the bass and the guitar. Vocalist Tony Kakko developed a clean singing style which relies both on falsetto and tenor voices and second guitarist Marko Paasikoski left the band. Kakko has stated that the change of sound was influenced by fellow Finnish power metal band Stratovarius.
