Question: Midwinter Graces is the eleventh solo studio album by an American singer-songwriter, pianist, and composer, whose vocal range is what?
Context: "A Silent Night with You" is a song written and performed by the American singer-songwriter, Tori Amos.  It was released November 29, 2009 as the only promotional single from the seasonal album "Midwinter Graces" (2009). Midwinter Graces is the eleventh solo studio album by singer-songwriter Tori Amos released on November 10, 2009 (November 16, 2009 in the UK), through Universal Republic Records.  It is the first seasonal album by Amos, and is also notable for marking her return to a more classical, stripped-down, baroque sound with various synths, string-instruments, the harpsichord and Amos's own signature "Bösendorfer" piano at center stage, once more.  The album, like previous releases from Amos, is available in a single form CD or a Deluxe edition which includes 3 bonus tracks, a 20-page photo book, and a DVD containing an interview with Amos.  The standard edition was not released in the US or Canada. Tenor is a type of classical male singing voice whose vocal range is between the countertenor and baritone voice types.  The tenor's vocal range (in choral music) lies between C, the C one octave below middle C, and A, the A above middle C.  In solo work, this range extends up to C, or "tenor high C".  The low extreme for tenors is roughly A♭ (two A♭ s below middle C).  At the highest extreme, some tenors can sing up to two Fs above middle C (F). "Spent the Day in Bed" is a song by English singer-songwriter Morrissey.  It was produced by Joe Chiccarelli.  The song was released via BMG Rights Management on 19 September 2017 as the lead single from Morrissey's upcoming eleventh solo studio album, "Low in High School" (2017). Gold Dust is the thirteenth solo studio album by American singer-songwriter Tori Amos, released on October 1, 2012 by Deutsche Grammophon and Mercury Classics.  The album is produced by Amos with arrangements by long-time collaborator John Philip Shenale.  Inspired by and following in a similar vein as Amos's previous effort, the classical music album "Night of Hunters" (2011), "Gold Dust" features some of her previously released alternative rock and baroque pop songs re-worked in an orchestral setting.  The material for "Gold Dust", consisting of songs selected by Amos spanning her entire catalogue from "Little Earthquakes" (1992) through "Midwinter Graces" (2009), was recorded with the Metropole Orchestra, conducted by Jules Buckley. Don't Be a Stranger is the eleventh solo studio album by the singer-songwriter Mark Eitzel.  It was released in October 2012 on Merge Records and produced by Sheldon Gomberg. 90 Millas ("90 Miles" in English, pronounced "no-VEN-ta Mi-yas" in Spanish) is the eleventh solo studio album by the Cuban-American singer-songwriter Gloria Estefan, and her fourth Spanish language album, coming after "Mi Tierra, Abriendo Puertas "and "Alma Caribeña."  It was released on September 17, 2007 by SonyBMG.  All original material, the album contains a selection of various Cuban rhythms mixed with Latin-American contemporary pop. A mezzo-soprano or mezzo ( , ; ] meaning "half soprano") is a type of classical female singing voice whose vocal range lies between the soprano and the contralto voice types.  The mezzo-soprano's vocal range usually extends from the A below middle C to the A two octaves above (i.e. A–A in scientific pitch notation, where middle C = C).  In the lower and upper extremes, some mezzo-sopranos may extend down to the F below middle C (F) and as high as "high C" (C). A countertenor (or contra tenor) is a type of classical male singing voice whose vocal range is equivalent to that of the female contralto or mezzo-soprano voice types, generally extending from around G to D or E, although a sopranist (a specific kind of countertenor) may match the soprano's range of around C to C. Countertenors often are baritones or tenors at core, but rarely use this vocal range in performance. Tori Amos (born Myra Ellen Amos, August 22, 1963 ) is an American singer-songwriter, pianist and composer.  She is a classically trained musician with a mezzo-soprano vocal range.
