Martyn P. Casey

Martyn P. Casey is an Australian rock bassist, best known as the anchor of Nick Cave and the Bad Seeds since 1990. With a career spanning four decades, he has also been a vital member of the Triffids and the Bad Seeds side project Grinderman. Known for his solid, melodic bass lines, Casey typically plays a Fender Precision Bass or Fender Jazz Bass. He has been a steady presence on every Bad Seeds album from Henry's Dream (1992) through Wild God (2024), contributing to the band's dark, atmospheric sound. Despite his low public profile, fans and critics regard him as one of rock's most dependable rhythm-section players.[edit]

Casey was born in Perth, Western Australia, to English-born parents who had emigrated from the UK. He grew up in the Perth suburb of Inglewood. Little is documented about his early childhood, but he developed an interest in music during his teenage years. He started on guitar before switching to bass. His first steps toward a career came when he joined local Perth bands, including a group called the Gentry. In the late 1970s, he moved to Melbourne to pursue music more seriously.

The pivotal moment came in 1980 when he answered an advertisement for a bassist placed by the emerging band the Triffids. He joined the Triffids and became a core member, contributing to their most acclaimed albums, including Born Sandy Devotional (1986) and Calenture (1987). Before music became his full-time career, he briefly worked as a postman in Australia.[edit]

After the Triffids disbanded in 1989, Casey moved to London. In 1990, Nick Cave invited him to join the Bad Seeds, replacing bassist Kid Congo Powers. Casey made his recording debut with the Bad Seeds on Henry's Dream (1992) and has remained a member ever since. He played on every subsequent Bad Seeds album, including Murder Ballads (1996), which featured the hit "Where the Wild Roses Grow" with Kylie Minogue, The Boatman's Call (1997), No More Shall We Part (2001), Abattoir Blues/The Lyre of Orpheus (2004), Dig, Lazarus, Dig!!! (2008), Push the Sky Away (2013), Skeleton Tree (2016), Ghosteen (2019), and Wild God (2024).

In 2007, Casey joined the Bad Seeds side project Grinderman, playing on their two albums, Grinderman (2007) and Grinderman 2 (2010). He has also collaborated with other artists, including recording and performing with Australian singer-songwriter Paul Kelly. As of 2026, Casey continues to tour with the Bad Seeds in support of Wild God.[edit]

Casey is portrayed in the media as a reliable, understated musician who lets his playing speak for itself. He has no signature style beyond his preference for Fender basses and simple, dark clothing on stage. There is no official fandom name for him individually; fan culture revolves around the Bad Seeds collective. He has no verified public social media presence and gives few interviews, maintaining a low profile that adds to his mystique as a quiet but essential member of the band.[edit]

The audience surrounding Martyn P. Casey does not rally behind a single individual with its own banner or chant. Unlike pop stars who command dedicated 'stan' armies, the fans of Nick Cave and the Bad Seeds operate as a collective entity, often identifying simply as 'Cavemen.' This group celebrates the band's dark atmospheric output rather than isolating specific members for separate fan clubs. There are no documented chart pushes, birthday billboards, or charity drives organized exclusively in Casey's name. While he is described by peers as a down-to-earth figure, the fanbase interaction remains one of collective appreciation for the music rather than a targeted movement focused on the bassist himself. His reputation rests on professional longevity and musical steadiness, avoiding the theatrical spectacle that often fuels viral folklore. One notable moment involves his violin playing overtaking guitar on the track 'Idiot Prayer,' a shift noted by critics as a significant sonic change. More recently, his absence from the 2024 UK and European tour due to illness drew public attention, with Colin Greenwood stepping in as a replacement. These events are matters of record rather than legendary myths. Despite his revered status as a phenomenal bass player within the indie community and his induction into the WAM Hall of Fame in November 2014, iFANN's Global Fame Engine has evaluated this person, but they do not currently hold a placement in the published rankings (Global Top 1,000 or a Top-100 scope list).[edit]

Martyn P. Casey originally played guitar before switching to the bass. Before launching his full-time music career, he worked as a postman in Australia. He has been a member of the Bad Seeds for over 30 years, making him one of the longest-serving members alongside Nick Cave and drummer Thomas Wydler. His bass playing on the Triffids' Born Sandy Devotional is considered a landmark in Australian rock. Known for his quiet, unassuming stage presence, he rarely gives interviews. A verified musical achievement occurred during the recording of 'Idiot Prayer,' where his violin work reportedly became the lead instrument, marking a distinct shift in the band's texture. In September 2024, news broke that Casey would miss the UK and European tour due to illness, leading to Colin Greenwood of Radiohead filling the bass spot. His contributions were formally recognized when he was inducted into the WAM Hall of Fame in November 2014.[edit]
