10 Best Hidden Tracks On Rock Music Albums

10. Slowdown - Unknown Road (Pennywise)

Forming in 1988, Pennywise are easily the world's favourite punk rock band named after a villainous clown from a Stephen King novel. It's a shallow pool, granted, but still...

The group released their self-titled debut album in 1991 and followed it up with 1993's Unknown Road. They would have their first taste of success with third album About Time, presumably because they threatened to pull everyone's brother down a storm drain if they didn't buy it.

Back to Unknown Road, the album considered by many to be Pennywise's real jumping-off point. In true punk fashion, it crams 13 songs into just 33 minutes, but the real number is actually one higher.

On the original tracklist, the album ends with Clear Your Head, but in reality there's another song straight after it. Slowdown, a rapid-fire three-minute jam, acts as the encore for this album, giving fans one last taste of Pennywise goodness.

When Unknown Road was remastered in 2005, Slowdown was officially recognised as being on the album. Although, if you check it out on Spotify, the song is still missing. If you want to hear it, you'll have to buy an actual physical CD.
