Plentzia (Plencia in Spanish) is a town and municipality located in the province of Biscay, in the Autonomous Community of the Basque Country, in northern Spain. The town has 4,146 inhabitants (2008).

Plentzia is located 27 km north-east of Bilbao. It is part of the Greater Bilbao metropolitan area, as well as being the terminus of the first line of the city's Metro. In addition to the Metro, two BizkaiBus bus routes serve the town, with further destinations served from Urduliz, the next stop on the Metro.

Plentzia is a resort town with a large beach beside the Plentzia River estuary, in the round, shell-shaped Bay of Plentzia, shared with neighbouring Gorliz and Barrika. The beach is very popular as it is clean and the sea is calm due to the shelter of the bay and the town has a lot of amenities for visitors.

Plentzia and its neighbouring municipalities are popular locations for better-off families from Bilbao to buy weekend–holiday homes and during the summer months the town's beach and bars and restaurants become much busier thanks to these residents and other visitors from Bilbao.

Michael Joseph Jackson (August 29, 1958 – June 25, 2009) was an American recording artist, entertainer, and businessman. Often referred to as the King of Pop, or by his initials MJ, Jackson is recognized as the most successful entertainer of all time by Guinness World Records. His contribution to music, dance, and fashion, along with a much-publicized personal life, made him a global figure in popular culture for over four decades. The seventh child of the Jackson family, he debuted on the professional music scene along with his brothers as a member of The Jackson 5 in 1964, and began his solo career in 1971.

In the early 1980s, Jackson became a dominant figure in popular music. The music videos for his songs, including those of "Beat It", "Billie Jean", and "Thriller", were credited with transforming the medium into an art form and a promotional tool, and the popularity of these videos helped to bring the relatively new television channel MTV to fame. Videos such as "Black or White" and "Scream" made him a staple on MTV in the 1990s. Through stage performances and music videos, Jackson popularized a number of complicated dance techniques, such as the robot and the moonwalk, to which he gave the name. His distinctive musical sound and vocal style influenced numerous hip hop, post-disco, contemporary R&B, pop and rock artists.
