The Baltimore-class cruiser (and the three ship Oregon City class sub-class) was a type of heavy cruiser in the United States Navy from the last years of World War II. Fast and heavily armed, ships like the Baltimore cruisers were mainly used by the Navy in World War II to protect the fast aircraft carriers in carrier battle groups. With their strong anti-aircraft armament, Baltimores could contribute especially in air defenses of these battle groups. Additionally, their 8-inch main guns and smaller medium guns were regularly used to bombard land targets in support of amphibious landings. After the war, only St Paul, Macon, Toledo, Columbus, Bremerton, Helena, Albany, and Rochester remained in service, while the rest were moved to the reserve fleet. All except Boston, Canberra, Chicago and Fall River were reactivated for the Korean War. By 1971, all ships remaining in the original design configuration were decommissioned, and started showing up in the scrap-sale lists. However, four Baltimore-class cruisers were refitted and converted into some of the first guided missile cruisers in the world, becoming two of the three Albany-class and two Boston-class cruisers. The last of these was decommissioned in 1980, with the Chicago lasting until 1991 in reserve. No example of the Baltimore class still exists.

Prince Rogers Nelson (born June 7, 1958), known by his mononym Prince, is an American singer-songwriter, multi-instrumentalist, and actor, and has been a major figure in popular music for over three decades. Prince is renowned as an innovator and is widely known for his eclectic work, flamboyant stage presence, and wide vocal range. He is widely regarded as the pioneer of Minneapolis sound. His music combines rock, R&B, soul, funk, hip hop, disco, psychedelia, jazz, and pop.

Prince was born in Minneapolis, Minnesota, and developed an interest in music at an early age, writing his first song at age seven. After recording songs with his cousin's band 94 East, 19-year-old Prince recorded several unsuccessful demo tapes before releasing his debut album For You in 1978, under the guidance of manager Owen Husney. His 1979 album Prince went platinum due to the success of the singles "Why You Wanna Treat Me So Bad?" and "I Wanna Be Your Lover". His next three records — Dirty Mind (1980), Controversy (1981), and 1999 (1982) — continued his success, showcasing Prince's trademark of prominently sexual lyrics and incorporation of elements of funk, dance, and rock music. In 1984, he began referring to his backup band as The Revolution and released Purple Rain, which served as the soundtrack to his film debut of the same name. A prolific songwriter, Prince in the 1980s wrote songs for and produced work by many other acts, often under pseudonyms.

Baltimore Pennsylvania Station (generally referred to as Penn Station) is the main transportation hub in Baltimore, Maryland. Designed by New York architect Kenneth MacKenzie Murchison (1872–1938), it was constructed in 1911 in the Beaux-Arts style of architecture for the Pennsylvania Railroad. It is located at 1515 N. Charles Street, about a mile and a half north of downtown and the Inner Harbor, between the Mount Vernon neighborhood to the south, and Station North to the north. Originally called Union Station because it served the Pennsylvania Railroad and Western Maryland Railway, it was renamed to match other Pennsylvania Stations in 1928.

The building sits on a raised "island" of sorts between two open trenches, one for the Jones Falls Expressway and the other the tracks of the Northeast Corridor (NEC). The NEC approaches from the south through the two-track, 7,660-foot Baltimore and Potomac Tunnel, which opened in 1873 and whose 30 mph limit, sharp curves, and steep grades make it one of the NEC's worst bottlenecks. The NEC's northern approach is the 1873 Union Tunnel, which has one single-track bore and one double-track bore.

Baltimore is a city in the state of Maryland in the United States.
