A solo artist is not something that is very common within the world of a cappella music, yet Eric manages to make it work somehow. Perhaps it is because being an a cappella solo artist is just another step in a long history of "uniqueness for him. If you look at his over 30 years in a cappella music, you see that he's always been different.
Normally, when people hear the word "a cappella", they don't think of modern rock/ pop music... unless it's an a cappella cover of a pop song. The music you hear from Eric is melodic-rock-inspired ORIGINAL songs (NO COVERS), created totally with the human voice or some other part of the anatomy.
But don't just take our word for it... listen for yourself, and ENJOY!
