Into the Skyline: Into the Skyline is the second studio album by English dance artist Cathy Dennis.  It was released in January 1993.  Written with an aim toward the U.S. market.  The album featured the singles "You Lied to Me", "Irresistible", "Moments of Love," "Falling", and "Why" - the latter was credited to D Mob with Cathy Dennis.  The album got to #8 in the UK Album Chart, whilst in the U.S. Billboard Hot 100, "You Lied to Me" was a Top 40 hit, and "Irresistible" made the Adult Contemporary Top Ten; however, the album descended the chart rapidly.  Dennis experienced a brief peak of fame, making a cameo in "Beverly Hills, 90210" singing the song "Moments of Love" (a minor U.S. Adult Contemporary chart hit), "Why" (in the episode, without D Mob) and "Touch Me (All Night Long)".  The Japanese edition had a second release of the album, which was called Into the Skyline +1, and featured three extra tracks: "Nothing Moves Me", a previous B-side, and "It's My Style" was released as singles.
