Background: General Sir Miles Christopher Dempsey,  (15 December 1896 - 5 June 1969) was a senior British Army officer who served in both world wars. As a junior officer, he fought in France during the First World War, where he was wounded, and served throughout the difficult interwar period, travelling to various corners of the globe. During the Second World War he had a close relationship with Bernard Montgomery and commanded the 13th Brigade in France in 1940, and spent the next two years training troops in England, before commanding XIII Corps for the invasions of Sicily and Italy in 1943. He later commanded the Second Army during the Battle of Normandy and made rapid advances in the subsequent campaign in Northern France and Belgium and was the first British Army commander to cross the Rhine.
Context: After the end of World War II in Europe, Dempsey was appointed to the command of the British Fourteenth Army and GOC in C Malaya Command and then Land Force Commander, South East Asia. By the time he had arrived however, the war in the East was also over. Within his command were 123,000 British and Dutch prisoners and nearly 750,000 captured Japanese.  Miles Dempsey, although modest and unassuming, was considered to be a highly competent officer. He asserted a very effective control over the British Second Army without taking the limelight. This was despite the stalemate in Normandy and the failure to advance beyond Antwerp and thus ensure that German forces remained isolated. He was claimed by military historian Carlo D'Este to be:  A career infantryman, Dempsey was an ardent student of military history and during the interwar period had frequently visited Europe to study its battlefields firsthand. Blessed with an active and incisive mind, a phenomenal memory and a unique skill in reading maps, Dempsey would soon leave his army staff in awe over his ability to remember everything he saw on a map, to bring a landscape literally to life in his mind even though he had never actually seen it. This talent proved particularly important during the crucial battles around Caen in June and July 1944. Dempsey was considered the Eighth Army's best expert in combined operations and, as he grew in experience, Montgomery soon recognized his potential for army command. The two men shared many qualities, including a disdain for paperwork and a determination, based on their First World War experiences, never to waste their soldiers lives.

Background: Carlos Santana  audio  (born July 20, 1947) is a Mexican and American musician who first became famous in the late 1960s and early 1970s with his band, Santana, which pioneered a fusion of rock and Latin American jazz. The band's sound featured his melodic, blues-based guitar lines set against Latin and African rhythms featuring percussion instruments such as timbales and congas not generally heard in rock music. Santana continued to work in these forms over the following decades. He experienced a resurgence of popularity and critical acclaim in the late 1990s.
Context: Carlos Santana's distinctive guitar tone is produced by PRS Santana signature guitars plugged into multiple amplifiers. The amps consist of a Mesa Boogie Mark I, Dumble Overdrive Reverb and more recently a Bludotone amplifier. Santana compares the tonal qualities of each amplifier to that of a singer producing head/nasal tones, chest tones, and belly tones. A three-way amp switcher is employed on Carlos's pedal board to enable him to switch between amps. Often the unique tones of each amplifier are blended together, complementing each other producing a richer tone.  He also put the "Boogie" in Mesa Boogie. Santana is credited with coining the popular Mesa amplifier name when he tried one and exclaimed, "That little thing really Boogies!"  Specifically, Santana combines a Mesa/Boogie Mark I head running through a Boogie cabinet with Altec 417-8H (or recently JBL E120s) speakers, and a Dumble Overdrive Reverb and/or a Dumble Overdrive Special running through a Brown or Marshall 4x12 cabinet with Celestion G12M "Greenback" speakers, depending on the desired sound. Shure KSM-32 microphones are used to pick up the sound, going to the PA. Additionally, a Fender Cyber-Twin Amp is mostly used at home.  During his early career Santana used a GMT transistor amplifier stack and a silverface Fender Twin. The GMT 226A rig was used at the Woodstock concert as well as during recording Santana's debut album. During this era Santana had also begun to use the Fender Twin, which was also used on the debut and proceedingly at the recording sessions of Abraxas.
