In a sense, Kid Rock could be considered a mad scientist.
Who else would consider pairing one of rap's pioneers with a co-founder of a legendary Southern rock band and bringing them on tour.
Not only that, who else could make the coupling -- Rev Run from Run D.M.C. and former Allman Brothers Band guitarist Dickey Betts -- seem natural.
Returning to Reading on Friday night two years after his last performance here, Rock's Rock & Roll Revival Tour gave the nearly packed Sovereign Center crowd a 21/2-hour bouillabaisse of Southern rock, rap, metal and country.
