Los Freneticos' previous LP "El Playa" was a great little surf album with plenty of nice tunes, but I didn't see a hint that they were heading towards something as ambitious as this. The description on their bandcamp page calls this "a lesson that reviews the A to Z of contemporary surf rock sound" (translated) and they certainly do make an effort towards that. I believe Los Freneticos are a quintet, but they frequently stretch out a bit further than that with an extensive cast of guest musicians playing flamenco, pedal steel, trumpets etc.
