There are multiple artists with this name: 1) Defender is a House band from France. This is a one-time collaboration between Alan Braxe, Fred Falke, and Savage. They've released only one mini-EP, called Defender, in 2005 on Vulture Music. It also appears to be the most successful Defender on last.fm. 2) Defender is a Chicago based band. The brainchild of childhood friends Jorge Ledezma (guitars, keyboards) and Gabi Meszaros (bass, keyboards) who began making home recordings and sound collages in the early 90's.
In 2005 after being friends and associated production whores with Mikah Freeman, Vance Musgrove & Ross McGrath started their digital label project, dubbed The Aston Shuffle. What started off as a group effort to get their previously unreleased tunes to the masses has skyrocketed into 2007 with the group heavily in demand for their white hot remixes
1- Shazam (not to be confused with band The Shazam) is producer Cameron Parkin from Perth, Western Australia. Getting releases pressed to vinyl since he was 16, his current output is somewhat along the lines of French House and Electro-Funk (in the truest/purest sense of the terminology). 2- Shazam is a German eurodance project produced by Graham Bonney, Andreas Herchenbach and Guido Scheffler.
Shazam released the singles "No Guarantee" and "Baby Baby Baby".
