After releasing
Stripped (2002) and collaborating with many different artists, Aguilera decided to record new old-school style materials for her upcoming album. She later explained that the lengthy break allowed her to write a lot about what she had experienced during that time. As a result,
Back to Basics, Aguilera's fifth studio album, is made up of two discs. Aguilera sent letters to different producers that she hoped could help her with the direction she was taking for the project, encouraging them to experiment, re-invent and create a modern soul feel. She described the first disc as "kind of a throwback with elements of jazz, blues and soul music combined with a modern-day twist, like hard-hitting beats". "Oh Mother" was written by Aguilera, Derryck Thornton, Mark Rankin, Liz Thornton,
Christophe Barratier,
Bruno Coulais and
Kara DioGuardi. Production was done by Big Tank and Q, with L Boggie credited as co-producer and Aguilera serviced as additional producer.
Piano and
keyboards were provided by V. Young, while
Rob Lewis served
guitar and arranging. Lewis also played
string instruments with Aroussiak Baltaian, Daniel Seidenberg, Garik Terzian, Ilana Setapen, Joel Pargman and Maia Jasper. ==Composition==
