Artist: Stone Age
Enter the French group, Stone Age. This self-titled album is their usual mix of celtic-style instruments with modern beats and (mostly) French lyrics. There's an odd tendancy for them to finish a song a minute or so before the track ends, and fill the rest with an apparently unrelated piece (listen to the end of "Kervador" for a good example of this).
Most of Stone Age's lyrics are in French, the exceptions being "Yesterday's Child" and "Reel Legend" (the latter reusing lyrics from the old song "What shall we do with a drunken sailor?". Interestingly, "Ti Plad" is one of those tracks which gradually speeds up in tempo, ala the Sailor's Hornpipe). Despite the largely incomprehensible nature of most of the lyrics to non-French speakers, the songs are very catchy and memorable.
