Question: Who is more of an independent artist, Pop Evil or Imogen Heap?
Context: "Just for Now" is a song by English recording artist and producer Imogen Heap, from her second studio album, "Speak for Yourself" (2005).  Written and produced by Heap, the song was originally written for the second-season episode of the television series "The O.C." entitled "The Chrismukkah That Almost Wasn't", but was deemed too dark for the episode.  "Just for Now" is a electronica song about a constant mayhem within a holiday environment, in which the singer sings to set aside the disarray for a short time of peace.  Heap has performed the song in live performances, which she invites the audience to participate on it.  "Just for Now" was covered by American recording artist Kelly Clarkson, for her sixth studio album "Wrapped in Red" (2013).  Her version of the song, produced by Greg Kurstin, musically quotes the Christmas standard "Carol of the Bells" and was met with positive reviews.  The song was also sampled in Clams Casino's composition "I'm God", featured on both "Instrumentals" and Lil B's "6 kiss", and was also covered by Pentatonix on their 2015 deluxe edition of their Christmas album That's Christmas to Me. Speak for Yourself is the second solo album by British singer Imogen Heap, following her collaborative effort with Guy Sigsworth as Frou Frou.  The album was released in the United States in 2005.  It was written, produced, arranged, and funded by Heap, without the backing of a record label, and features guest appearances from Jeff Beck, who does a guitar solo on "Goodnight and Go", and Heap's ex-boyfriend, Richie Mills, who argues with her on "The Moment I Said It". Guy Sigsworth is a British composer, producer and songwriter.  During his career he has worked with many artists, including Seal, Björk, Goldie, Madonna, Britney Spears, Kate Havnevik, Imogen Heap, Bebel Gilberto, Mozez, David Sylvian, Alanis Morissette, Eric Whitacre and Alison Moyet.

He was previously a member of the band Frou Frou together with Imogen Heap. Pop Evil is an American rock band that was formed in North Muskegon, Michigan in 2001 by Leigh Kakaty.  He then added Dave Grahs, Dylan Allison, and Jamie Nummer.  Later, guitarist Tony Greve was added as a temporary studio musician for the band but was invited to become a full-time member in early 2007.  Around that time, bassist Jamie Nummer left the band for personal reasons and was replaced by Matt DiRito, formerly of Archangel and Before the Fire.  In 2011 Allison had major neck surgery and Chachi Riot (formerly of "Saraph") filled in.  In 2012 Riot became a mainstay as Pop Evil's drummer.  In 2012 due to personal reasons, Greve quit the band on his own accord and Nick Fuelling stepped up to fill his shoes. Leo Matthew Abrahams (born 1977 in Camden, London) is an English musician, composer and producer.

Since 2005 he has released five solo albums, largely in an ambient style involving complex arrangements and a use of guitar-generated textures.  He has also co-written or arranged a variety of film soundtracks, including Peter Jackson's 2009 release "The Lovely Bones" and Steve McQueen's "Hunger".
