Reggae rock: Reggae rock is a subgenre of reggae fusion and rock music that primarily uses the genres reggae, rock and ska.  The term "reggae rock" has been used to categorize bands like The Police, Sublime, Sublime with Rome, Pepper, Slightly Stoopid, The Expendables, Iration, the Dirty Heads, Rebelution, 311 and, to some extent, heavier bands such as Fishbone and Bad Brains.  The term "reggae metal" has been used to describe bands that combine reggae rock with heavy metal, such as Dub War, Skindred and Zeroscape.  Reggae rock found its rise in popularity in the 1990s in Long Beach, California, with the band Sublime.  The genre has lately found a boost in popularity with the 2010 song "Lay Me Down" by the Dirty Heads featuring Rome Ramirez from Sublime with Rome, which peaked at number 1 on both the US "Billboard" Alternative Songs and Rock Songs charts.

Second-hand Smoke: Second-hand Smoke is a compilation album by the band Sublime.  It was released in 1997 following the death of lead singer Bradley Nowell the year before.  Although this is technically a compilation album, it features some unreleased material as well as recycled and remixed versions of previous tracks.  It is also regarded as their final album.  Even though the surviving members of Sublime (Eric Wilson and Bud Gaugh) stated that the band would not make any more albums after Nowell's death, which would result in the band's breakup, MCA bound them by their contract and made the remaining members follow out their contract with the next 3 albums.  Instead of recording more albums with Sublime, Wilson and Gaugh would record together in their later projects Long Beach Dub Allstars and Sublime with Rome.
