It DOESN'T all sound the same. As proof, I offer the delightful polka "Carmelita", which adds texture-changing tuba and accordion arpeggios on the chorus. There's also a slow cumbia later in the album called "Agua Bendita", and it's gringo-accessible touches like these that help Huracanes stand out from the packs of polkas and waltzes that occupy the regional Mexican charts.
But even when the songs DO start to sound samey, Huracanes are worth hearing for their singers' close harmonies, their lead singer's rich tone, and their accordion players' inventiveness. We're not just talking flashy runs of notes, here -- the accordionists (I'm pretty sure there's more than one) buzz and float around the singer like clouds of gnats, or comp like jazz pianists, jamming chords into whatever spaces they can find. Listen to more here; way better than Ricky Martin's Musica Alma Sexo (but you knew that).
