No stranger to success, Led Zeppelin is back on the charts again. After the group’s 1969 debut cracked Billboard‘s top 10, each of Zep’s next eight albums went to either No. 1 or 2. And now, more than 10 years after breaking up in the wake of drummer John Bonham’s death, Zeppelin has returned with a 54-track boxed set, Led Zeppelin, which entered the Billboard chart at No. 40 and then leapt to 18 the following week. The set is the most expensive release ever to hit the top 20, testimony to just how popular Led Zeppelin remains today. ”It’s doing very well,” says a spokeswoman at Atlantic Records. A Tower Records manager in New York expects sales ”will really start to move at Christmas.” Also fueling the resurgence of Zep-mania is the first single from the boxed set, the previously unreleased ”Travelling Riverside Blues,” which peaked early in November at No. 7 on Billboard‘s chart of Album Rock Tracks. Videos for both ”Travelling Riverside Blues” and the 1973 song ”Over the Hills and Far Away” are also getting play on MTV, which recently weighed in with a ”Whole Lotta Zep” weekend-long tribute. Where will it all end? Most likely, as the song says, over the hills and a long way away.
