What do you call a rock music channel without no music?

A Rock Music channel without any music would typically be referred to as a "talk show" or "talk radio" channel, where hosts and guests discuss various topics related to rock music, such as history, trends, and news. It may also be called a "rock music podcast" if the content is available for on-demand listening. The absence of music would differentiate it from traditional rock music channels that play music continuously.
