Problem: Michael Kevin Taylor (born 17 January 1949) is an English musician, best known as a former member of John Mayall's Bluesbreakers (1966-69) and the Rolling Stones (1969-74). He has appeared on some of the Stones' classic albums including Let It Bleed, Sticky Fingers and Exile on Main St..

Taylor was born to a working-class family in Welwyn Garden City, but was raised in Hatfield, Hertfordshire, England, where his father worked as a fitter (machinist) for the De Havilland aircraft company. He began playing guitar at age nine, learning to play from his mother's younger brother. As a teenager, he formed bands with schoolmates and started performing concerts under names such as The Juniors and the Strangers. They also appeared on television and put out a single. Part of the band was recruited for a new group called The Gods, which included Ken Hensley (later of Uriah Heep fame). In 1966, The Gods opened for Cream at the Starlite Ballroom in Wembley. In 1965, at age 16, Taylor went to see a John Mayall's Bluesbreakers performance at "The Hop" Woodhall Community Centre, Welwyn Garden City. On the night in question, I had gone to The Hop with some guys from our band, former schoolmates and Ex-Juniors Mick Taylor and Alan Shacklock. It was after John Mayall had finished his first set without a guitarist that it became clear that for some reason Eric Clapton was not going to show up. A group of local musicians, which included myself, Robert 'Jab' Als, Herbie Sparks, and others, along with three local guitarists--Alan Shacklock, Mick Casey (formerly of the Trekkas) and Mick Taylor--were in attendance. Taylor himself has said after seeing that Clapton hadn't appeared, but that his guitar had already been set up on the stage, he approached John Mayall during the interval to ask if he could play with them. Taylor mentioned that he'd heard their albums and knew some of the songs, and after a moment of deliberation, Mayall agreed. Taylor amended, "I wasn't thinking that this was a great opportunity... I just really wanted to get up on stage and play the guitar." Taylor played the second set with Mayall's band, and after winning Mayall's respect, they exchanged phone numbers. This encounter proved to be pivotal in Taylor's career when Mayall began to look for a guitarist to fill Peter Green's vacancy the following year. Mayall contacted Taylor, and invited him to take Green's place. Taylor made his debut with the Bluesbreakers at the Manor House, an old blues club in north London. For those in the music scene the night was an event... "Let's go and see this 17-year-old kid try and replace Eric". Taylor toured and recorded the album Crusade with John Mayall's Bluesbreakers. From 1966 to 1969, Taylor developed a guitar style that is blues-based with Latin and jazz influences. He is the guitarist on the Bluesbreaker albums Diary of a Band, Bare Wires, and Blues from Laurel Canyon. Later on in his career, he further developed his skills as a slide guitarist.

Problem: The Merchandise Mart (or the Merch Mart, or the Mart) is a commercial building located in the downtown Loop, of Chicago, Illinois, United States. When it opened in 1930, it was the largest building in the world, with 4,000,000 square feet (372,000 m2) of floor space. The art deco landmark is located at the junction of the Chicago River's branches. The building is a leading retailing and wholesale destination, hosting 20,000 visitors and tenants per day as of the late 2000s.

The Merchandise Mart was modernized in the late 1950s and 1960s. The Indian chiefs were removed and replaced with concrete plates in 1961, of minimal note to onlookers as skyscrapers did not rise on the north side of the river as predicted. Some of the carvings were later found in a suburban backyard and auctioned in 2014. In 1962, an entrance canopy was constructed over the south for vehicle use. In 1977, Skidmore, Owings & Merrill designed the Chicago Apparel Center, located on the west side of Orleans Street, which increased the Merchandise Mart's total floor space to 6,200,000 square feet (580,000 m2). Making use of plazas, esplanades and overlooks employed the waterfront location for pedestrian pleasure. In 1988, Helmut Jahn designed an enclosed pedestrian walking bridge over Orleans Street connecting the Mart and the Apparel Center. After a 10-year, $100 million modernization in the late 1980s that included public utility upgrades, Beyer Blinder Belle's commission in 1989 was to create additional perimeter entrances and restore the display windows, main entrance and lobby. On the south facade, the drive-through canopy was removed and two smaller doorways aside the main entrance were added. Display windows, painted over during the earlier modernization campaign, were restored with clear glass to showcase merchant's wares. New main and corner entrances were added to the rear facade, and the loading dock that occupied the north portion of the first floor of the river level was removed in order to use the bottom deck of North Bank Drive. Improvements to the lobby included restoration of the original glass curtain wall over the entrance, shop fronts and reception desk using terrazzo floors and wall sconces influenced by the original design. The project was completed in 1991. In November 2007, the building received LEED for Existing Buildings Silver recognition.
