In the mid-'90s, ska music experienced a brief revival. This list is the best ska music of that era had to offer. Before anyone makes the comment, Sublime is not on this list because they were not a true ska band, although they were awesome. Without further adieu:
5: The Mighty Mighty Bosstones - The Impression That I Get was one of the most commercially successful ska songs of the '90s, by one of the most commercially successful ska bands of its time. Many properly credit The Mighty Mighty Bosstones with bringing ska to the masses (along with No Doubt). Not a personal favorite, but good enough for 5 on the list.
4: Save Ferris - Originally seen as a watered down version of No Doubt, Save Ferris developed a unique and interesting sound. They quickly turned into a pop band, but their legacy is forever cemented in ska history with their golden achievement--an amazing cover of Come On Eileen (often misattributed to No Doubt).
3: Dance Hall Crashers - Check out the album Honey, I'm Homely! for a perfect example of everything right with ska music--clever lyrics and fast, upbeat, harmonic sounds. Part of Dance Hall Crashers' appeal is that they are fronted by two women with interesting and unique harmonies. They're just cool, man.
2: No Doubt - Gwen Stefani looked awesome and sounded even better in the early days of No Doubt. No Doubt's Tragic Kingdom is one of the best and most successful ska albums ever, and although the band was a huge commercial success, good music is good music, regardless of who listens or how popular it is, so it's forgivable.
1: Reel Big Fish - Sell Out, She Has a Girlfriend Now, a great cover of Take On Me, and an appearance in BASEketball propel Reel Big Fish ahead of No Doubt, but barely. The most raw sound on this list, Reel Big Fish just sounded like they had fun with everything they did.
So, that's my list. Anyone you think I missed or short-changed?
