Ether was an experimental music project by John Watts, released under the name Fischer-Z.
 After releasing two successful solo albums and one album of remixes, since the last Fischer-Z album, "Stream", John Watts had started to take an interest in creating big beat music.
 After creating a whole big beat style album in 1999 entitled "Bigbeatpoetry", Watts carried on in a similar style for "Ether".
 He recorded a number of songs, featuring only his guitar and voice, and then put them over cut-up beats as a rhythm track.
 Watts had also added a filmic touch to the project, he travelled throughout Europe and post-9/11 New York City to find musicians at random and record them using his laptop, in their homes and on the street.
 Sarah Vermeersch filmed & edited the process into a road movie.
 "Ether" was further released as a John Watts solo album (see: Ether Music & Film), including the road movie DVD and a CD of tracks from the "Ether" album that appeared in the movie.

Grove Street Cemetery or Grove Street Burial Ground in New Haven, Connecticut, is located adjacent to the Yale University campus.
 It was organized in 1796 as the New Haven Burying Ground and incorporated in October 1797 to replace the crowded burial ground on the New Haven Green.
 The first private, nonprofit cemetery in the world, it was one of the earliest burial grounds to have a planned layout, with plots permanently owned by individual families, a structured arrangement of ornamental plantings, and paved and named streets and avenues.
 This was "a real turning point... a whole redefinition of how people viewed death and dying", according to historian Peter Dobkin Hall, with novel ideas like permanent memorials and the sanctity of the deceased body.
 In part for this reason, it was designated a National Historic Landmark in 2000.
 Many notable Yale and New Haven luminaries are buried in the Grove Street Cemetery, including fourteen Yale presidents; nevertheless, it was not restricted to members of the upper class, and was open to all.
