       This Month, the Rock Doc is honored to  feature one of the very best and most musically eclectic podcasts in the country! I’m talkin about “The Imbalanced History of Rock and Roll,” a nationally known rock music podcast hosted by two very experienced DJ’s/radio hosts Ray Koob and Markus Goldman!

      Recently Ray and Markus had the rock doc (see below) on for a podcast episode. I was simply blown away with their “DEEP” knowledge of  not only rock music but so many styles of music that contributed to the history of rock and popular music in general! Check out how they so skillfully weave tons of music example into each and every one of their podcast episodes! Folks, their podcasts are a LOT OF FUN!

This podcast that was created to discuss the humongous tree of music known as Rock and Roll. There are thousands of branches. The history is fuzzy, scattered, known and unknown. There is so much information out there already with even more to be learned. Together, we are going to have fun talking about our passion, the Imbalanced History of Rock and Roll. Between us, we have 50+ years of rock and roll radio experience and a thirst to know more that hasn’t been quenched. Together, with your input we want to begin to balance the imbalanced. We look forward to connecting and sharing with you as we  dig deep into the  music.

About Ray Koob…

     A Rock n’ Roller since birth, and growing up in the ‘60s & ‘70s, I’ve been a student of Rock n’ Roll, its cast of characters, the events, the triumphs, the tragedies, and the amazing high of a great song, all my life! First I fell in love with radio, then the idea of being on the radio. I bought records, loved Top 40, discovered FM radio, bought more records, started my high school radio station, bought more records, worked at a variety of college stations, bought more records…

     In time, I got my break, and I started working at radio stations. I stopped buying records…  Later I caught on at Friday Morning Quarterback, a major trade paper, and helped lead the Metal/Grunge charge of the ‘90s! I never thought I’d have to buy another record. Along the way, I became friends with a small record label President, and went to work for him for 5 years!

     All of that led me back to Philadelphia every day, and a chance to be on the air in my hometown. And that is what has led me to this point, and this podcast. Markus and I have experienced some stuff, and we want to tell you about it, and some other cool shit we have learned about the music we love along the way! And I’ve resumed buying records…

About Markus Goldman…

     The love of music was definitely in my blood from birth. At about the age of 6 months, my grandfather was busted by my mother for feeding me chocolate and dancing me around the living room in the middle of the night to Marvin Gaye, the Mama’s & Papa’s, Otis Redding, Elvis and so much more. From what I was told by my grandmother, this happened quite a few times. From there the love grew.

     At the age of 9, I purchased my first full album with my own money, “Bigger Than Both Of Us,” by Hall & Oates. It was a glorious moment in my life. Also around that time, during those early years, I would spend many a night up late reading Hardy Boys books listening to Rock Radio in Denver, saying, “that’s what I want to do when I grow up.” By the time I was in high school, I was full on into music. Buying albums, cassettes, listening to radio and making mix tapes. I also got involved with the high school radio station, further cementing my path. In college, I did radio and then took a break when I got my degree and began a career as a copywriter in Denver. Hated it.

     Fell back into radio by chance in ’92 and have been doing radio since. Wouldn’t have it any other way. Stations I have worked at over the decades, 100.3KMJI FM – Denver, 92X KNRX -Denver, 106.7 KBPI Denver, 96.5 The Peak – KXPK Denver and 93.3FM WMMR – Philadelphia. I am a lucky mother fucker. I love music dearly and know for a fact that a life filled with good music is a happy fulfilled life. As a lover of music, one of my favorite conversation topics is music. Rock and Roll is a big beautiful tree with a lot of branches that make for exciting conversation. We hope you will join us in this inexact, imperfect imbalanced journey for conversation, spirits and of course great music.

Talkin’ Tunes With The Rock Doc, Dr. Rob Brosh!


Here are three previous episodes of “The Imbalanced History of Rock and Roll” Podcasts that all document the history of Led Zeppelin, The Yardbirds, and the blues based” scene of London in the late 1950’s thru the 1970’s!


Rock and Roll Family Trees are an adventure once you climb up them. One of the thickest and richest family trees is The Yardbirds Family Tree. We automatically tend to consider the three guitar gods immediately, Eric Clapton, Jeff Beck and Jimmy Page and their magnificent histories in bands like Cream, Led Zeppelin, Derek & The Dominos among others. Our digging and research surprised us as to where The Yardbirds family tree led to, and excited us with new discoveries. We were also able to have a quick conversation with Yardbirds original drummer, Jim McCarty, who was able to confirm and deny these leaves of rock and roll diversity on the Yardbirds Family Tree.

The largest branch in The Yardbirds’ Family Tree is more like a split in the trunk of the thing. Breaking out “The Hammer” this time as we explore a band made for and played for the fans: Led Zeppelin!

Digging Into One Of Rock’s Greatest Albums

The Imbalanced Brothers take a close look into Led Zeppelin’s fourth album. Call it IV, or Runes, or ZoSo, it’s amazing, and this episode takes you through it, track by track. Markus and Ray get into the locale for recording, Headley Grange, and the “Stairway” court case!  Time to flip on the headphones (earbuds will suffice) and dig into Led Zeppelin IV!
