The question is how you define "New Blood" - if you talk about "New Blood", the current PG-project with Gabriel-songs rearranged with orchestra - that takes us back to January 2010 or December 2009 I think, when PG first mentioned tracks like "Rhythm of the Heat" and "In Your Eyes" with orchestra and the following tour "New Blood Live 2010".
Some contacts of PG with classic musicians takes us back to the summers of 1991 and 1992: the so-called "Real World Recording Weeks I and II. Beside many and various musicians from all over the world Peter also met people like Nigel Kennedy ("Vivaldi`s four seasons"), the cello-player Caroline Lavelle, Alex Gifford and his fantastic classic instrumental piece "Morecambe Bay" and many others. Some of these partly classic tracks and musicians were featured on the Real World-album "Arcane" by Assorted Artists, a cousin-album to the later on released "Big Blue Ball"-album.
During the various recording sessions for "UP" and "OvO" - maybe 1998 - some more classic artists like Jocelyn Pook showed up at Real World and released albums. Peter also tried out new ideas with strings, brass, horns - some classic arrangements actually with classic musicians. He recorded one song for the movie "Babe Pig in the City" with Randy Newmann (199

, a track produced by Bob Ezrin, who also worked on the brass arrangement of "My Head sounds like That", a track to appear on the "UP"-album in 2002. Ezrin and Peter already did some fine orchestral stuff back in 1977 in combination with rock-sound.
The album "OvO" then released in 2000 included many string arrangements and Peter also added some strings to "Signal to Noise". A track called "Book of love" for the "Shall We Dance"-soundtrack (2004) also featured string arrangements.
the rest idea for orchestra was born in a thread in spring 2009, when Dolce Vita and I were discussing an idea about Peter appearing on stage with a full classic orchestra in the back for "Signal To Noise", but that`s a legend:-]. . .
