IV is the fourth studio album by American rock band Winger.
 According to frontman Kip Winger, one morning he "just woke up and heard the new Winger record" in his head, knowing just what he wanted to do with it.
 It was released in October 2006 on Frontiers Records.
 The album cover was done by DC comic book artist Ethan Van Sciver known for his artwork on titles such as Green Lantern, Flash, Superman, and Batman.
 Kip Winger was introduced to Van Sciver by a mutual friend of theirs in Florida.
David Michael Draiman (born March 13, 1973) is an American songwriter and the vocalist for the band Disturbed as well as for the band Device.
 Draiman is known for his distorted voice and percussive singing style.

 Draiman has written some of Disturbed's most successful singles, such as "Stupify", "Down with the Sickness", "Indestructible", and "Inside the Fire".
Karma is the fifth studio album by American rock band Winger.
 The album was released on 16 October 2009 in Europe and 27 October 2009 in the United States.
 The inspiration for a new Winger came about at the end of 2008, when Kip Winger had the vision to meld the more commercial, heavier and song-oriented approach of the first two albums with the more "thinking-man" approach of the last two studio records.
"Madalaine" the debut single by American rock band Winger, from their self-titled debut album "Winger".
 Released in 1988, the song reached #27 on the Mainstream rock "Billboard" charts.
 According to Kip Winger, it was one of the first four songs he and band mate Reb Beach wrote when they first got together, based on a handful of riffs Reb had from when he was younger.
 Kip figured out how best to arrange the riffs, enabling the pair to complete the song.
Heart Like a Gun is the third studio album by singer Fiona, released in 1989 through Atlantic Records.
 It reached #150 on the "Billboard" 200 chart in 1990 and remained charted for sixteen weeks.
 The album features singer/bassist Kip Winger and drummer Rod Morgenstein from the band Winger, with Kip dueting with Fiona on "Everything You Do (You're Sexing Me)".
"Seventeen" is a single released by the American rock band Winger, from their album "Winger".
 Released in 1988, the song charted at No. 26 on the "Billboard" Hot 100.
 Despite its pop metal sound, Kip Winger points out that the tune is musically a progressive song and that it is actually quite challenging to play and sing simultaneously.
 Along with Headed for a Heartbreak, it is Winger's most popular song for which they are most remembered.
Charles Frederick Kip Winger (born June 21, 1961) is an American rock musician, a member of the rock band Winger, and a solo artist.
Songs from the Ocean Floor is the third solo studio album by American rock artist Kip Winger.
