Angelo "MadDog" DiSipio
Radio Legend & Pop Culture Aficionado
With an unmistakable voice, electric personality, and a career spanning over four decades, MadDog DiSipio is a bona fide broadcasting legend. With 45 years of experience in both radio and television, MadDog has become a trusted name and a beloved personality in the world of entertainment media.
MadDog’s journey began in the golden era of FM radio in New York (TV-Radio Legend Joe Frankin) and Philadelphia, mentored by personailites like Jerry Blavat, Hi Litt, Joe Niagara, George Michael, Bobby Charger and Super Lou Serafine just to name a few, where he quickly rose through the ranks thanks to his dynamic presence, encyclopedic knowledge of music, and deep connection with his audience.
Over the years, he has worked in top markets, interviewed music’s biggest icons, and helped shape the soundtrack of generations. Known for his raw energy, sharp wit, and deep love of pop culture, MadDog continues to bring that same fire to the mic as the host of America’s Popcast, What’s The Buzz.
Broadcasting coast to coast, What’s The Buzz dives into the heart of music, entertainment, and nostalgia—all through MadDog’s signature style: authentic, passionate, and just a little bit wild.
After 45 years, he's not slowing down—he's just getting louder.
Stay tuned. Stay buzzed. That’s the MadDog way.

Callum “Big Cal” Yeater has officially arrived at WTBR—seatbelt unbuckled, mic wide open, and ready to send the Popcast into brand-new, beautifully bizarre territory. Equal parts thoughtful commentator and chaos-adjacent instigator, Big Cal brings a sharp ear for culture, a soft spot for deep cuts, and a willingness to follow any tangent to its logical (or illogical) conclusion.
Known for turning offhand observations into full-blown segments and asking the question everyone else wisely avoided, he thrives in the space where curiosity meets comedy. Whether he’s dissecting pop culture ephemera, championing an underdog take, or calmly escalating a bit far past its breaking point, Big Cal’s presence adds texture, momentum, and just the right amount of unpredictability.
At WTBR, his role is simple: push the conversation, challenge the premise, and keep the Popcast honest—if not always on track. Buckle up.
Cal is also an actor who has appeared with Danny McBride & John Goodman in HBO/MAX TV's "The Righteous Gemstones" & Danny McBrides, "Vice Principals" ... Cal was featured with Walton Goggins (Uncle Baby Billy Gemstone)
