Billy Joel's Piano

==Origin== Billy Joel is a musician notable for many pop-rock albums and singles over a nearly 40-year career. Perhaps his most famous album was The Stranger, which is his best selling non-compilation album and was certified diamond, meaning at least 10,000,000 sales. This Bösendorfer piano was used in the recording of the album and the concerts that followed, and presumably became an artifact in part due to the monstrous success of The Stranger.

Effects
The artifact is technically activated by playing it, although it affects people that hear music from the piano, except the pianist themselves. Due to the variety of messages that songs on The Stranger stated, this artifact was imbued with the ability to affect different groups of people differently. Men are encouraged to embrace their talents and do what they love instead doing a job for material gain, as "Movin' Out (Anthony's Song)" states. Women are encouraged to accept and love who they are and not to change for anyone, as "Just the Way You Are" and "She's Always a Woman" state. Children are encouraged to live life to the fullest and stop rushing into becoming an adult, as "Vienna" states. Children refers to people aged 16 or under.

It also has a relationship with Billy Joel's Harmonica, joining in with Piano Man on piano whenever the harmonica is activated. It's regular effects do not seem to be prevalent when playing with the harmonica.

Collection
After many Billy Joel concerts between the release of The Stranger and the artifact collection date, many men, women and children from across the United States began exhibiting similar behaviours, although each group of people had a specific behaviour with no overlap. As the people were so far apart and had no logical way of coming into contact with each other, much of the research was done at the Warehouse. It was found, via credit card statements, that almost all of the affected people had purchased tickets to a Billy Joel concert. Several Billy Joel concerts were attended by Artie Nielsen, who deduced that the piano was the artifact. Travelling to New York City, the next concert location, Artie built an exact replica of the Bösendorfer piano, a famously complex brand, using George Harrison's Copy of "He's So Fine". It was later swapped late at night at Carnegie Hall, and shipped back to Warehouse 13.
