Two of the most successful and adventurous bands to emerge from the New Wave follow one another at the Merriweather Post Pavilion -- on Tuesday it's the Talking Heads, who have multiplied and prospered by finding the primeval art beat that eluded Blondie; and on Wednesday, the recently mellowed Elvis Costello and the Attractions will undoubtedly expand on the frequently spare arrangements of wordy masterpieces from the new "Imperial Bedroom" album.
