Martin Karl "Max Martin" Sandberg (born February 26, 1971) is a Grammy-nominated,[1] Swedish pop-dance music producer and songwriter. He was born in Stockholm, Sweden and is best known by his artistic name Max Martin. As a producer and songwriter, he crafted a string of worldwide hits for pop artists like the clean-cut boy bands The Backstreet Boys and *NSYNC, Britney Spears, Swedish starlet Robyn and the Swedish eurodance star E-Type among many others, in the mid/late '90s to mid 2000s.

His trademark is a bouncing, piano/synth-heavy pop sound that mixes music styles such as Europop and Italo house with classic American Bandstand pop arrangements. However, with Kelly Clarkson's hits "Since U Been Gone" and "Behind These Hazel Eyes", which propelled Max back into the spotlight in 2004, he had managed to reinvent himself with a fresh pop rock sound.

Martin Sandberg grew up in Stenhamra, Ekerö Municipality, a suburb of Stockholm. As a teenager he sang in several bands before joining a glam-style metal band called It's Alive in 1985 as their singer and frontman. It's Alive were formed by ex LAZY members Per Aldeheim and Kim Björkgren on guitars, and John Rosth who had been a member of Lineout. Martin eventually dropped out of high school to pursue a career in music with his band under the nickname "Martin White". In 1988 they participated in the national rock championships and also played as the in-house band at a disco in Cyprus. The band got a breakthrough in 1991, as Dave Constable of Megarock Records offered them to make a demo-record. The later debut album was originally pressed in 1,000 copies and later on given away as a free cover tape in the UK by the Metal Forces magazine.
