Why are Columbia promo boss Peter Gray and loyal lieutenants Brady Bedard and John Strazza each piloting a massive tour bus around neighborhoods across the USA? We're glad you asked.

The three weasel musketeers have divided up the top Pop programming chains and taken their mighty machines (now repurposed in the age of no touring) to the homes of key programmers, bringing said PDs aboard to play them the hotly anticipated new BTS single, "Dynamite," which premieres on 8/21 on all major radio outlets with an official impact of 8/25.
