Bob Siebenberg

Robert Layne Siebenberg (born October 31, 1949), also known as Bob C. Benberg, is an American musician, best known as a member of British progressive rock band Supertramp, playing drums and percussion. He was the sole American in Supertramp's lineup, joining the band in 1973. His son, Jesse, joined Supertramp at the time of the release of the live album It Was the Best of Times (live; 1999). In 1985, Siebenberg released a solo album called Giants in Our Own Room (and credited to "Siebenberg"), where he sings lead on half of the songs and also plays keyboards and drums. Joining Siebenberg on this record were Scott Gorham of Thin Lizzy fame (Gorham was Siebenberg's brother-in-law from 1969 to 2000), Steve Farris of Mr. Mister, Procol Harum drummer B. J. Wilson (who played on the final track), bassist Kerry Hatch of Oingo Boingo, and Supertramp bandmate John Helliwell. An old friend, Derek Beauchemin, joined in to co-write and play keyboards. Prior to joining Supertramp, Siebenberg was a member of pub rock band Bees Make Honey as well as RHS, an American band. He was in a band called "Heads Up" which released the 1989 album The Long Shot. Joining Siebenberg were his writing partner Dennis O'Donnell, Mark Hart, Brad Cole, John Helliwell, Marty Walsh and again, Scott Gorham on guitar. In 1989, Siebenberg composed the original music for Sierra On-Line's video game Space Quest III. He endorses Drum Workshop drums, pedals and hardware, Paiste cymbals, Remo heads and Regal Tip drumsticks. In the 1970s, he used Ludwig drums.[edit]

Supertramp devotees have long celebrated Bob Siebenberg as the band's American heartbeat, a figure whose steady percussion anchored hits like "Breakfast in America" and "The Logical Song." Fans often mark his birthday on October 31st with social media tributes that highlight his unique status as the sole non-British member of the classic lineup from 1973 to 1983. While the broader Supertramp community discusses his contributions alongside Rick Davies and Roger Hodgson, there is no formal, dedicated name for a fanbase solely focused on him; instead, supporters identify collectively through shared appreciation of his drumming and his 1985 solo effort, Giants in Our Own Room. This album remains a cult favorite among those who follow his work beyond the band, particularly noting his lead vocals and keyboard work alongside Thin Lizzy's Scott Gorham. Despite decades of touring and a significant legal victory in August 2025 where an appeals court ruled he was owed royalties from the 1970s hits, Siebenberg has not generated specific viral legends or organized fan rituals unique to his persona. The iFANN Global Fame Rankings do not yet include him, leaving his precise standing in the wider cultural landscape undefined by current metrics. His son Jesse joining the group for the 1999 live album It Was the Best of Times added a generational layer to his legacy, but this familial connection remains part of the band's narrative rather than a standalone fandom phenomenon. Without documented campaigns, subway ads, or exclusive events attributed specifically to him, his reputation rests on the consistent quality of his performance and the enduring popularity of the records he helped shape. Fans continue to discuss his role in interviews and forums, treating his contributions as essential knowledge for any serious student of progressive rock history.[edit]
