Julian Pavone was certified as of March 21, 2010, when he was 5 years 10 months and 3 days old.
The rules for London-based Guinness say a drummer must play on at least one commercial record and be paid for the work. The drummer also must have given at least 20 concerts of 45 minutes or longer within five years.
Julian is 7 and lives in Macomb County's Macomb Township, about 25 miles north-northeast of Detroit. His family says Julian began playing drums at 3 months.
