Since 1994, James Lavelle and Tim Goldsworthy have been creating unique and diverse tracks as Unkle, which once included DJ Shadow, who has always been favorite of mine. This British collaboration has had a series of guest artists on their albums, the first being Psyence Fiction in 1998. I fell in love the first time I heard it.
Since then, they have released four other albums and continue to showcase their talent for mixing different styles of music but keeping a certain sound that is only owned by them. The album art for Psyence Fiction has a collage and grafitti-esque feel expressed through various tones of brown and texture. A nice palette to look to for a neutral foundation.
