From Billboard to the MTV VMAs, Macklemore & Ryan Lewis have solidified themselves as one of the biggest rap acts in the country. That goes for overseas too, where the Seattle duo began a 90-date tour last month.

As part of Buffalo David Bitton's "Blank Check Series," Macklemore & Ryan Lewis will be giving fans an in-depth look at their lives on the road with the "World Tour" documentary series. Above is part one, which features footage from their performances in London, Birmingham, Glasgow, Dublin, Amsterdam, Zurich and Paris.
