A lineup befitting its Twitter-happy crowd: 6/19 RTG @ WAC = MGMT, SJ&DK, OKG + RGC.

Translation, for those not up on abbreviated hipster music tweets: The June 19 installment of Rock the Garden at Walker Art Center will feature New York electronic-rock stars MGMT, soul revivalists Sharon Jones & the Dap Kings, treadmill-dancing pop-rock quartet OK Go and Duluth indie-rock trio Retribution Gospel Choir.

The Current (89.3 FM) announced the lineup for the Walker's seventh almost-annual garden party Tuesday afternoon in a broadcast from Brit's Pub.

Tickets are available for Walker and Minnesota Public Radio members only through April 27, when they go on sale to the public for $40 via the Walker's box office (612-375-7600 or walkerart.org/tickets). VIP tickets are $75 or $150.

This year's RTG will once again be laid out on a grassy, amphitheater-like hill next to the museum where the Guthrie Theater used to stand -- the same site that was a hit last year when the Decemberists headlined the sold-out event.

In other concert news, last season's glammed-up "American Idol" runner-up Adam Lambert -- returning this week to the TV show that made him -- announced a new tour coming June 12 to Mystic Lake Casino. Tickets go on sale May 1 through Ticketmaster for $69 and $59.

Also, the Minnesota Zoo's summer music series has been beefed up, with five new additions, headed by the July 3 return of '80s electro-pop heroes Devo, who are reuniting for a new album and this weekend's Coachella Music Festival. Tickets go on sale May 3 for $56.

Other new zoo shows include a cappella group Straight No Chaser (June 6), Larry Graham with Mint Condition (June 18), the Wailers (June 26) and Squeeze with the English Beat (July 26).
