    DISGRACELAND

    DISGRACELAND is an award-winning music and true crime podcast about musicians getting away with murder and behaving very badly. Jerry Lee Lewis's 5th wife? Dead. Sid and Nancy? Both dead. Why? Because musicians are insane, and insane things happen to them. Why did we lose Amy Winehouse at 27? Was Debbie Harry really abducted by Ted Bundy as she claims? Is Patti Smith not just the "Godmother of Punk", but also the "Original True Crime Girl"? What really happened the night of the Jay Z nightclub stabbing? What do the Diddy indictments truly reveal? All these stories and more, on artists from every genre and their true crimes, in our massive 260-plus story archive. The Dead, the Stones, Johnny, Willie, Frank, Kurt, Courtney, Gaga, Lana, Taylor, and too many to name. DISGRACELAND is music history come to life through audio storytelling as you've never heard it before, with revealing facts: yes, assassins are the real reason the Beatles quit touring—reclaimed myths: no, Mama Cass didn't die from choking on a ham sandwich––and constant reckoning between art and artist––all told through the lens of true crime. This is the podcast for the self-proclaimed "Disgos", the musically obsessed and the true crime heads; the outsiders, the independent thinkers who know that the best history is the history that gets buried. DISGRACELAND is where host Jake Brennan tells the stories they didn't want told. The kind you'll end up telling someone else. Get ready to uncover hidden truths and buckle up for truly edge-of-your-seat storytelling. New, fully scripted, sound-designed episodes are released every Tuesday. Bonus chat-style episodes where Jake responds to voicemails, texts, and emails from Disgos hit on Thursdays, and "Rewind" episodes from our archive drop on Sundays. DISGRACELAND is not a journalistic podcast. It's an entertainment podcast inspired by true events. Certain dialogue and scenes are dramatized, as is common in scripted entertainment based on real stories. Sources and credits for each episode are available at www.disgracelandpod.com. To unlock ad-free listening, exclusive content, and connect with your fellow Disgos, go to www.disgracelandpod.com to become an All Access member. Rocka Rolla.
