Sunday nights in August have taken on a particularly friendly feel with the “Song Exchange” series at the Cedar. In the vein of Live Letters’ Evening With Friends, those intimate shows that reveal mutual respect and collaborations between artists, Song Exchange puts two groups on stage that each perform their own sets, in addition to playing a few covers of the opposite act’s songs. It’s a merging of genres and generations in this case, with two Duluth born acts in Dead Man Winter and Charlie Parr. Dead Man Winter, a side project of Trampled By Turtles frontman Dave Simonett, rests in an easy folk-driven vibe, slower than TBT’s usual frenetic pace and almost country-inspired. Charlie Parr lives the roots music he plays, which he’s been perfecting long before it came back into style. Vintage equipment makes his sound as authentic as his intentions with his records, so you know this shared stage will be all humble admiration and sincere respect. Watch these greats interact tonight and you’ll almost feel like a fly on the wall of a private practice session. 7:30 p.m. $18 in advance, $20 at the door. —EK
