Query: Great original rock band!

"Yesterday's Tomorrow", a 2-disc set, has been making the rounds on my cd player pretty frequently for the past several months. Both cds are full of awesome, original rock music - Some of it sexy, some angry, some sweet. The electric cello really adds to their originality and takes the music to another level. Formula 151 definitely has "it".
