Two touring mainstays of 89.3 the Current's playlist, two Minnesota-bred veteran indie-rock acts and one rowdy dance floor ringleader are lined up to play this year's Rock the Garden concert June 15 outside Walker Art Center.

Canadian synth-rock quartet Metric will headline, joined by another band with indie cred and mainstream radio success, Los Angeles's Silversun Pickups. Locally rooted music heroes Bob Mould and Low — neither of whom have ever played RTG despite long ties to RTG co-organizers the Current and the Walker — will round out the bill along with Baltimore electronic wiz Dan Deacon.

Tickets are $55 and go on sale to Walker and Minnesota Public Radio members starting Friday at 11 a.m. If any are left over Saturday, they will go on sale to the general public then. Don't expect any to be on sale Saturday, though: All 10,000 tickets have gone to members the past two years. Get the full details at RocktheGarden2013.com.

He wonders if stutter affected 'Idol' stint

"American Idol" contestant Lazaro Arbos won the hearts of viewers not just because of his singing, but because of his personal story. The 22-year-old from Florida suffers from a severe stutter that disappears while he's performing. Though the Cuban-born performer acknowledges that his speech impediment got him attention, he doesn't think it won him votes. He went on to say that if he didn't stutter, he thinks he would have lasted longer on the show. Arbos placed sixth on "Idol," which airs Wednesdays and Thursdays on Fox. He was voted off last week and was the last male competitor this season. Arbos will hit the road when the "Idol" contestants launch a tour this summer.

For the past seven years, he was LSO president — a title previously held by only four other conductors, including Leonard Bernstein.
