The loins (or: lumbus) are the sides between the lower ribs and pelvis, and the lower part of the back. It is often used when describing the anatomy of humans and quadrupeds (such as horses,pigs or cattle). The anatomical reference also carries over into the description of cuts of meat from some such animals, e.g. tenderloin or sirloin steak.

In human anatomy the term "loin" or "loins" refers to the side of the human body below the rib cage to just above the pelvis. It is frequently used to reference the general area below the ribs. While the term "loin" is generally not used in medical science, some disorders do contain it.

The lumbar region of the spinal column is located in the loin area of the body.

The spinal column consists of five regions: cervical, thoracic, lumbar, sacral and coccygeal. That means "lumbar" is the third region.

The term also has become euphemistic for human genitals due to their prominence in that anatomical region. Because of this euphemistic use of the term, the article of clothing that is worn around the genital area has been named a loincloth.

Yann Tiersen (born 23 June 1970) is a musician from France. His musical career is split between studio albums, collaborations and film soundtracks with a distinctive sound that is always involved. It can be recognized by its use of a large variety of instruments; primarily the guitar, synthesizer or violin together with instruments like the melodica, xylophone, toy piano, harpsichord, accordion and typewriter.

Tiersen is often mistaken as a composer of soundtracks, himself saying "I'm not a composer and I really don't have a classical background", but his real focus is on touring and studio albums which just happen to often be suitable for film. His most famous soundtrack for the film Amélie was primarily made up of tracks taken from his first two studio albums.

Yann Tiersen was born in Brest in the Finistère département in Brittany in northwestern France, in 1970, into a family of Belgian and Norwegian origins. He started learning piano at the age of four, violin at the age of six, and received classical training at several musical academies, including those in Rennes, Nantes, and Boulogne. In the early 1980s when he was a teenager he was influenced by the punk subculture, and bands like The Stooges and Joy Division. In 1983, at the age of 13, he broke his violin, bought an electric guitar, and formed a rock band. Tiersen was now living in Rennes, and this turned out to be the perfect place for his musical career. In fact, Rennes is home to the three-day music festival Rencontres Trans Musicales, held annually in December, giving him the opportunity to see acts like Nirvana, Einstürzende Neubauten, Nick Cave and the Bad Seeds, The Cramps, Television, and Suicide. A few years later, when his band broke up, Tiersen bought a cheap mixing desk, an 8-track reel-to-reel audio tape recording, and started recording music solo with a synthesizer, a sampler, and a drum machine.
