Federal bankruptcy judge on Friday approved sale of California-based Tower Records to Great American Group, which plans to liquidate the music retailer.

After almost 30 hours of what attorneys described as “robust” and “vigorous” bidding, Great American won with a bid of $134.3 million, beating Trans World Entertainment, which had hoped to continue operating at least some Tower stores, by only $500,000.

Tower said it has been hurt by an industrywide decline in music sales, downloading of online music and competition from big-box stores such as Wal-Mart.

Peter Gurfein, an attorney representing Tower Records, said the company will be sold for an aggregate of $150 million, including the sale of various leases and properties.

Gurfein said Great American plans to begin the liquidation process and going out of business sales on Saturday.
