Can We Start Calling Indie Rock Groups An Orchestra?

[Seil]

So I was thinking about this a bit - I'm a fan of the classics. By that I mean people like Chopin, Mozart, Bach, Beethoven, and Haydn. Also, having a mum who works musically - with an orchestra - and growing up with musical theater, I always envision an orchestra as a large collection of different musicians and their instruments following the lead of someone having a seizure.

However, I think that as generations go on, the idea of an orchestra might change. I don't know if these would qualify, but would you consider Ra Ra Riot an orchestral piece? They're not lead by a conducter, but neither are Broken Social Scene, and... oh, they're roughly the same thing.

Ra Ra Riot is an American indie rock band from Syracuse, New York, consisting of vocalist Wes Miles, bassist Mathieu Santos, guitarist Milo Bonacci, cellist Alexandra Lawn, violinist Rebecca Zeller, and drummer Gabriel Duquette.

Broken Social Scene are a Juno Award-winning Canadian indie rock band, a musical collective currently including nineteen members, formed in 1999 by Kevin Drew and Brendan Canning. All of its members currently play in various other groups and solo projects, mainly based around the city of Toronto. The band refuses the label "supergroup," based on size or the ubiquity of their members, claiming that in the indie scene everyone is involved in more than one project. The group's sound could be considered a combination of all of its members' respective musical projects, and is occasionally considered baroque pop.[citation needed] It is characterized by a very large number of sounds, grand orchestrations featuring guitars, horns, woodwinds, and violins, unusual song structures, and an experimental, and sometimes chaotic production style from David Newfeld, who produced the second and third albums.

So are these guys orchestral already, or what?
