Four Four Two

Kieran Hebden, best known by the stage name Four Tet, is an English post-rock and electronic musician. Hebden first came to prominence as a member of the band Fridge before establishing himself as a solo artist. Hebden's music originally eschewed the traditional pop song format in favour of a more abstract approach - his sound and melodies incorporate elements of hip hop, electronica, techno, jazz, grime and folk music with live instrumentation. His newer works are inspired heavily by house music.

The Natural Four began their quest for stardom in Oakland, CA, in the mid-'60s, landing their first deal with a local outfit called Boola Boola Records. Initially, they had two 1969 releases on Boola Boola – "You Did This for Me" and "Why Should We Stop Now" – that did well in the San Francisco/Oakland area. ABC Records took over distribution and pushed "Why Should We Stop Now" to number 31 R&B in 1969. At this junction the group consisted of lead singer Chris James, Allen Richardson, John January, and Al Bowden.
Three more releases followed on ABC: "The Same Thing in Mind," an old Boola Boola track named "I Thought You Were Mine," and a remake of the Temptations' "Message From a Black Man." Nothing approached even the minimal success of "Why Should We Stop Now," and their relationship with ABC ended on a sour note.

Without using the customary Clifford algebras frequently studied in connection with the representations of orthogonal groups, this book gives an elementary introduction to the two-component spinor formalism for four-dimensional spaces with any signature. Some of the useful applications of four-dimensional spinors, such as Yang–Mills theory, are derived in detail using illustrative examples.
