Some context: Burt Freeman Bacharach ( BAK-@-rak; born May 12, 1928) is an American composer, songwriter, record producer, pianist, and singer who has composed hundreds of popular hit songs from the late 1950s through the 1980s, many in collaboration with popular lyricist Hal David. A six-time Grammy Award winner and three-time Academy Award winner, Bacharach's songs have been recorded by more than 1,000 different artists. As of 2014, he had written 73 US and 52 UK Top 40 hits. He is considered one of the most important composers of 20th-century popular music.
Bacharach's music is characterized by unusual chord progressions, influenced by jazz harmony, with striking syncopated rhythmic patterns, irregular phrasing, frequent modulation, and odd, changing meters. He arranged, conducted, and produced much of his recorded output. Sometimes called "easy listening", he has expressed apprehension regarding that label. According to NJ.com contributor Mark Voger, "It may be easy on the ears, but it's anything but easy. The precise arrangements, the on-a-dime shifts in meter, and the mouthfuls of lyrics required to service all those notes have, over the years, proven challenging to singers and musicians." Bacharach's selection of instruments included flugelhorns, bossa nova sidesticks, breezy flutes, molto fortissimo strings and cooing female voices. According to editors of The Mojo Collection, it led to what became known as the "Bacharach Sound." He explains:  I didn't want to make the songs the same way as they'd been done, so I'd split vocals and instrumentals and try to make it interesting ... For me, it's about the peaks and valleys of where a record can take you. You can tell a story and be able to be explosive one minute then get quiet as kind of a satisfying resolution.  While he didn't mind singing during live performances, he tried to mostly avoid it on records. And when he did sing, he explains, "I try to sing the songs not as a singer, but just interpreting it as a composer and interpreting a great lyric that Hal [David] wrote." When performing in front of live audiences, he would often conduct while playing piano., as he did during a televised performance on The Hollywood Palace, where he played piano and conducted at the same time.

Some context: Martin Sandberg (born 26 February 1971), known professionally as Max Martin, is a Swedish songwriter, record producer and singer. He rose to prominence in the second half of the 1990s after making a string of major hits for artists such as the Backstreet Boys, Britney Spears and NSYNC. Some of his earlier hits include "...Baby One More Time" (1998)
"I didn't even know what a producer did, I spent two years-day and night-in that studio trying to learn what the hell was going on." - Max Martin, 19 March 2001.  In 1993, Martin was hired by Cheiron Studios and spent some time learning the basics, before the first production collaboration between PoP and Martin: the Rednex song "Wish You Were Here" in 1994. They both worked on Ace of Base's second album, The Bridge (1995), shortly thereafter, as well as on albums by 3T, Army of Lovers and Leila K. To date, The Bridge has sold more than six million copies worldwide, including one million in the United States. When Martin eventually left his band It's Alive in late 1995, he was replaced by Anders Jansson.  In 1995, the Cheiron Studios was hired by Zomba to work on Backstreet Boys' self-titled debut album Backstreet Boys (1996). Zomba became the main working partner since the success in 1995. Martin took part in the production of "Quit Playing Games (With My Heart)" (1996), co-written with Herbie Crichlow, a single which quickly went platinum and climbed to No. 2 on the Billboard Hot 100, as well as the singles "As Long As You Love Me" (1997) and "Everybody (Backstreet's Back)" (1997). The album was not released in the U.S. until 1997, but was released overseas and caught on all across Europe, eventually selling around 8 million copies worldwide. This led to the Backstreet Boys being relaunched in their home country later on, this time more successfully. Later that year, Martin co-wrote and co-produced Robyn's hits "Show Me Love" and "Do You Know (What It Takes)" which ended up on the Billboard Hot 100 top 10.  In 1998, Cheiron Productions worked on albums by Five and Jessica Folcker. Jessica Folcker had first been hired as a backing singer for tracks with Ace of Base and Dr. Alban, and her debut album Jessica became an instant hit with singles like "Tell Me What You Like" and "How Will I Know Who You Are" which both sold platinum. After Denniz PoP died of cancer that same summer, Martin took over as director of Cheiron Studios. He soon started working with writer/producer Rami Yacoub, who continued to be his partner for many years. Martin also wrote two songs with Bryan Adams during this time, "Cloud Number Nine" and "Before The Night Is Over."
