Blastissimo 

N, blah-STEE-seemo slang term meaning fucking loud as shit.

My director wasn’t happy with my triple Fortissimo so I cranked my guitar to Blastissimo.

Blastissimo 

Music that is so loud the quality decreases. A term used by acoustic musicians for when the volume of music is so great the actual sound is distorted as a result. This is similar to how screaming isn't just louder than speaking, but also raspier. Blastissimo doesn't have a set decibel level, nor is it defined by audience preference, but defined by the ability of musician and instrument to produce melodious sounds.

Play it louder

Louder!
**
I SAID LOUDER!

JUST FORGET ABOUT PLAYING IT RIGHT AND PLAY IT AT BLASTISSIMO!
