The Moody Blues

The last track from 1988's Sur la Mer, "Deep."  Unfortunately, it's a slideshow (no official video was ever made), but the slide show isn't too bad.  I believe this is the closest the band has ever gotten to doing a song blatantly about sex.  Still, the instrumental bit at the end is one of my favourites.

The title track from 1986's The Other Side of Life.  One of the band's best songs from the 1980s with its dark, moody textures.  And the video has some nice visuals (most of which don't make a whole lot of sense--I believe even the band doesn't even have a clue).

And no reference to The Moody Blues would be complete without a mention of "Nights in White Satin." :D
