Howie Klein, a visionary music executive who championed the punk and new wave movements before becoming a prominent political activist, has died at the age of 77. He passed away on Wednesday after a battle with cancer. Klein was a co-founder of the influential 415 Records in San Francisco and later served as the president of Reprise Records, where he played a pivotal role in the careers of artists such as The Ramones, The Pretenders, and Green Day.

Klein's career began in the counterculture of the late 1960s, where he made a name for himself as a music journalist and radio DJ. His ear for authentic, cutting-edge sound led him to the executive suite, but he never lost his rebel spirit. Known for his "artist-first" philosophy, he was beloved by musicians for his genuine passion and integrity in an industry often driven by bottom lines.

After retiring from the music business in 2001, Klein reinvented himself as a progressive political blogger and activist. He founded the "DownWithTyranny!" blog and the Blue America political action committee, tirelessly fundraising for progressive candidates and causes. His fearless voice and commitment to democratic values made him a significant figure in grassroots politics.

Klein's impact spanned two distinct worlds—music and politics—leaving an indelible mark on both. He is remembered by friends and colleagues as a man of boundless energy, sharp wit, and an unwavering commitment to making the world a louder, fairer place.
