In the wake of Led Zeppelin's reunion concert at London's O2 Arena on Monday, NME reported Wednesday that the band's album sales have increased 500% in the United Kingdom. Additionally, music retailer HMV told NME that the recent compilation album by the group, Mothership, had risen by 50% in the first night after the concert and was the "biggest selling album in HMV stores" on Tuesday. NME also notes that the increase in sales of Led Zeppelin products is not limited to music. An HMV spokesman told the magazine "this demonstrates the enduring appeal of Led Zeppelin as the definitive rock band. Their music is now connecting with a whole new generation of fans, who are discovering its brilliance for the first time."

In addition to the new compilation Mothership, Led Zeppelin's catalog also received a boost after the reissue of the 1976 concert soundtrack The Song Remains the Same and a new version of the accompanying film. The band also joined fellow classic acts by joining the digital market, with a "Complete Led Zeppelin" becoming available in Apple Inc. (NASDAQ: AAPL)'s iTunes Store the same day the new compilation was released in stores.

Following the success the band has enjoyed with the reunion concert and the sales increases, rumors are now circulating that the band will embark on a full scale worldwide reunion tour, and enter the studio to prepare new material for the first time in nearly thirty years. These rumors aside, the success the band is experiencing is certainly a welcome site for the band and the music industry. There is no doubt that a full scale world tour and/or new material would only continue this success, but until the rumors are confirmed fans can enjoy the images of the band performing on Monday, as well as the solid catalog that is now available in both physical and digital mediums.
