unusual trio?

i recently purchase a cd from a group i've never heard of,
ADD trio.the cd was on sale so i went for it, that was a week ago and still i can't get it of my player.this group is composed of drums, guitar and flute.my question is , what other unusual trio configuration should i check out.
Alex Skolnick Trio. Alex was the guitarist from the heavy metal group Testament. Now touring and promoting there cd in a jazz trio of guitar, double bass and drums with tunes from Ozzy, Aerosmith, Scorpians and others. Something different, but nicely done.
