Sen. Richard Blumenthal is calling for the federal enforcement of the Boss and Swift Act, a law designed to help bring ticket transparency after recent incidents of high prices for concerts and computer crashes when customers try to make purchases online.

The law went into effect at the start of the month. The federal enforcement of the law would require sellers to provide more information about the base price of tickets, hidden ticketing fees and more detailed refund policies.

The measure is supported by Live Nation, one of the biggest names in the concert business. They host nearly 40,000 shows and sell 500 million tickets per year.
