Bedrock

In stratigraphy, bedrock is consolidated rock underlying the surface of a terrestrial planet, usually the Earth. Above the bedrock is usually an area of broken and weathered unconsolidated rock in the basal subsoil. The surface of the bedrock beneath soil cover is known as rockhead in engineering geology and identifying this, via excavations, drilling or geophysical methods, is an important task in most civil engineering projects. Superficial deposits (also known as drift) can be extremely thick, such that the bedrock lies hundreds of meters below the surface.

Bedrock may also experience subsurface weathering at its upper boundary, forming saprolite.

A solid geologic map of an area will usually show the distribution of differing bedrock types, i.e., rock that would be exposed at the surface if all soil or other superficial deposits were removed.

Soil scientists use the capital letters O, A, B, C, and E to identify the master soil horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons—the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but such a horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation). Hard bedrock, which is not soil, uses the letter R.

BedRock

"BedRock" is the second single by hip hop group Young Money Entertainment from their debut collaboration album We Are Young Money. It is performed by Young Money artists Lil Wayne, Gudda Gudda, Nicki Minaj, Drake, Tyga, Jae Millz, and features R&B singer Lloyd. It was released as a CD in the United Kingdom on March 22, 2010. "BedRock" is featured as a bonus track on the Japanese and New Zealand editions of Nicki Minaj's debut studio album, Pink Friday.

Background

After being leaked in September 2009 to Lil Wayne fan sites, "BedRock" was finally released on November 14, 2009. It was originally titled "Girl You Know" (the fan sites to which the single was leaked titled it "BedRock/Girl You Know") and the chorus was sung by Omarion and Lil Wayne's verse was different, but due to Omarion's departure from Young Money, he was replaced by Lloyd. The song was originally planned to be released as the 3rd official single of the album, however due to popular demand by fans it was released as the 2nd single.

Listen (Emanuel and the Fear album)

Listen is the first full-length album from Brooklyn-based symphonic rock band Emanuel and the Fear and was released via Paper Garden in March 2010.

Critical reception

Regarding Emanuel and the Fear's first full-length record, The 405 wrote: "The haunting mish-mash of psychedelia, poetic lyrics, pop and post-rock is tremendously put together and while a little overblown at times, it never gets in the way of the clarity of any song. Mixing The National's sentimentality with the integrity of Eels, a dedicated cult following already awaits."
