Tune into 89.3 The Current at 4pm to hear Walker performing arts curator Philip Bither and The Current’s Mary Lucia announce the lineup for Rock the Garden on June 20 – this festival has become one of summer’s coveted tickets. Speaking of tickets, they go on sale tomorrow too, but Walker and MPR members get first dibs. If you’re looking for an excuse to join, this is as good as it gets. Oh wait, it gets better: Your ticket is free if you contribute at $60 or more; tickets for you and a friend are free if you renew or joining at $150 or more. As you listen to Mary and Philip playing songs from the bands, check out images from Rock the Garden last year – and picture yourself this June, soaking up sun and great sounds in our grassy back yard.
