Posted for the word more than for the music. The Digg post was entitled "Tina S Continues To Be The Shred Queen Of YouTube With Her Cover Of 'Altitude'."
So I had to look up "shred."
Urban Dictionary, in its usual semi-helpful way defines it as "technically and rhythmatically [sic] hammering out amazing and lightning-fast solos on a guitar. 2. To play so amazingly fast on guitar you almost destroy it's strings."
During my search I found the word used more often with regard to snowboarding than to music. And the 'net in its infinite variety offered up a snowboarding dictionary, where "to shred" is "to tear up the terrain" or "to carve with intensity."
For the etymology of the stem word I turned to Wiktionary:
From Old English screade (from which also screed), cognate with German Schrot (“small shot”), Swedish skrot, Old Norse skrydda (“shrivelled skin”), from Proto-Indo-European *(s)kreu (“cutting tool”), extended form of *(s)ker- (“to cut”).(I find it interesting that screed is related). Wiktionary goes on to define the snowboarding "shred" in terms of "aggressiveness" and the music "shred" in terms of speed.
Now I open it up to readers to come up with the appropriate nuances and contexts for the use of the word. Also - is she that good? or is the "shred queen" appelation just hype?
