Underground is a 1941 war film about the German Nazi Resistance opposing the Nazis in World War II. Jeffrey Lynn and Philip Dorn play two brothers initially on opposite sides.
Underground is the second studio album by the American garage rock band, The Electric Prunes, and was released in 1967 on Reprise Records. It would be the final album of any materialized input by band members until the 1969 "New Improved" Electric Prunes were formed. The album was a moderate chart hit, but, without a hit-ready single, the band could not repeat their past success.
The album, Underground, brought changes to the band once recording began. Limited lyrical input plagued the band's creative process on their debut. Only one track, composed by Mark Tulin and James Lowe, called "Lovin'" was included on their first album. This changed with this album because Dave Hassinger, the group's producer, was not as active in the sessions resulting in nine of the 12 tracks becoming the band's own material. With so much more musical freedom, the band could mold their music into their own image. The final products were a more direct and cohesive set of songs that reflected the band's own design.
Underground is an album by guitarist Phil Keaggy, released in 1983, on Nissi Records. It is a collection of demo tracks recorded by Keaggy in his home studio.
The album was re-released in 2000 on CD by the Phil Keaggy Club, and features a different track order.

A top is a toy designed to be spun rapidly on the ground, the motion of which causes it to remain precisely balanced on its tip because of inertia. Such toys have existed since antiquity. Traditionally tops were constructed of wood, sometimes with an iron tip, and would be set in motion by aid of a string or rope coiled around its axis which, when pulled quickly, caused a rapid unwinding that would set the top in motion. Today they are often built of plastic, and modern materials and manufacturing processes allow tops to be constructed with such precise balance that they can be set in motion by a simple twist of the fingers and twirl of the wrist without need for string or rope.
The motion of a top is produced in the most simple forms by twirling the stem using the fingers. More sophisticated tops are spun by holding the axis firmly while pulling a string or twisting a stick or pushing an auger. In the kinds with an auger, an internal weight rotates, producing an overall circular motion. Some tops can be thrown, while firmly grasping a string that had been tightly wound around the stem, and the centrifugal force generated by the unwinding motion of the string will set them spinning upon touching ground.
A top is clothing that covers at least the chest, but which usually covers most of the upper human body between the neck and the waistline. The bottom of tops can be as short as mid-torso, or as long as mid-thigh. Men's tops are generally paired with pants, and women's with pants or skirts. Common types of tops are t-shirts, blouses and shirts.
The neckline is the highest line of the top, and may be as high as a head-covering hood, or as low as the waistline or bottom hem of the top. A top may be worn loose or tight around the bust or waist, and may have sleeves or shoulder straps, spaghetti straps (noodle straps), or may be strapless. The back may be covered or bare. Tops may have straps around the waist or neck, or over the shoulders.
In mathematics, the category of topological spaces, often denoted Top, is the category whose objects are topological spaces and whose morphisms are continuous maps or some other variant; for example, objects are often assumed to be compactly generated. This is a category because the composition of two continuous maps is again continuous. The study of Top and of properties of topological spaces using the techniques of category theory is known as categorical topology.
N.B. Some authors use the name Top for the category with topological manifolds as objects and continuous maps as morphisms.
Like many categories, the category Top is a concrete category (also known as a construct), meaning its objects are sets with additional structure (i.e. topologies) and its morphisms are functions preserving this structure. There is a natural forgetful functor
to the category of sets which assigns to each topological space the underlying set and to each continuous map the underlying function.
