Fred Keller (Mandolin & Vocals), is theWhistlepigs chief songwriter and ethnomusicologist. He has an uncanny knack of finding the most bizarre and unusual songs from the strangest sources. Who else would have turned up the gem from the band's CD Unjugged, "I Picked Up A Hammer and Knocked Him in the Head" and made it into a hit single? But most impressive is Fred's ability to write a bluegrass song that sounds like it could have been written a hundred years ago, but is completely free of cliche."
