The Outer Hebrides (Scottish Gaelic: Na h-Eileanan Siar, IPA: [nə ˈhelanən ˈʃiəɾ]) also known as the Western Isles and the Long Island, is an island chain off the west coast of Scotland. The islands are geographically contiguous with Comhairle nan Eilean Siar, one of the 32 unitary council areas of Scotland. They form part of the Hebrides, separated from the Scottish mainland and from the Inner Hebrides by the waters of the Minch, the Little Minch and the Sea of the Hebrides. Scottish Gaelic is the predominant spoken language, although in a few areas English speakers form a majority.

Most of the islands have a bedrock formed from ancient metamorphic rocks and the climate is mild and oceanic. The 15 inhabited islands have a total population of about 26,500 and there are more than 50 substantial uninhabited islands. From Barra Head to the Butt of Lewis is roughly 210 kilometres (130 mi).

There are various important prehistoric structures, many of which pre-date the first written references to the islands by Roman and Greek authors. The Western Isles became part of the Norse kingdom of the Suðreyjar, which lasted for over 400 years until sovereignty was transferred to Scotland by the Treaty of Perth in 1266. Control of the islands was then held by clan chiefs, principal of whom were the MacLeods, MacDonalds, Mackenzies and MacNeils. The Highland Clearances of the 19th century had a devastating effect on many communities and it is only in recent years that population levels have ceased to decline. Much of the land is now under local control and commercial activity is based on tourism, crofting, fishing, and weaving.

The Hebrides ( /ˈhɛbrɨdiːz/; Scottish Gaelic: Innse Gall) comprise a widespread and diverse archipelago off the west coast of Scotland. There are two main groups: the Inner and Outer Hebrides. These islands have a long history of occupation dating back to the Mesolithic and the culture of the residents has been affected by the successive influences of Celtic, Norse and English-speaking peoples. This diversity is reflected in the names given to the islands, which are derived from the languages that have been spoken there in historic and perhaps prehistoric times.

A variety of artists have been inspired by their Hebridean experiences. Today the economy of the islands is dependent on crofting, fishing, tourism, the oil industry and renewable energy. The Hebrides lack biodiversity in comparison to mainland Britain, but these islands have much to offer the naturalist. Seals, for example, are present around the coasts in internationally important numbers.

The Hebrides have a diverse geology ranging in age from Precambrian strata that are amongst the oldest rocks in Europe to Tertiary igneous intrusions.

David Howell Evans (born 8 August 1961), more widely known by his stage name The Edge (or just Edge), is a musician best known as the guitarist, backing vocalist, and keyboardist of the Irish rock band U2. A member of the group since its inception, he has recorded 12 studio albums with the band and has released one solo record. As a guitarist, The Edge has crafted a minimalistic and textural style of playing. His use of a rhythmic delay effect yields a distinctive ambient, chiming sound that has become a signature of U2's music.

The Edge was born in England to a Welsh family, but was raised in Ireland after moving there as an infant. In 1976, at Mount Temple Comprehensive School, he formed U2 with his fellow students and his older brother Dik. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most popular acts in popular music, with successful albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, The Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, The Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally contributed lyrics. The Edge met his second and current wife, Morleigh Steinberg, through her collaborations with the band.

Paul Halley (born 1952 in Romford, England) is an keyboardist, vocalist and composer. He is perhaps best known as being a member of and composer for the Paul Winter Consort.

Paul Halley was born in England in 1952 and sang in the choir of St. Matthew's Church, Ottawa, when his family migrated there. At age 16 he became an Associate of the Royal Conservatory of Toronto and won an organ scholarship to Trinity College, Cambridge. While organist and choirmaster at the Cathedral of St. John the Divine, 1977 to 1989, he collaborated with Paul Winter to create the Missa Gaia/Earth Mass, Halley became a member of the Paul Winter Consort, and earned five Grammy Awards for his contributions as a composer and performer with the group. He left the Consort in 1999 after recording Journey With The Sun to pursue a solo career. Paul Halley's compositions have been performed and recorded by the New Jersey Symphony and John Williams and the Boston Pops Orchestra.

After leaving the Cathedral in 1989, Halley founded Joyful Noise, Inc., a non-profit organization designed to teach children proper vocal technique, music theory, and musicianship. The two groups involved with the organization are Chorus Angelicus and Gaudeamus.
