Internal Bleeding

Internal Bleeding is widely credited as one of the primary architects of 'slam' death metal, a subgenre that emphasizes mid-tempo, percussive grooves over the high-speed tremolo picking common in Florida death metal. Formed in Long Island in 1991, they emerged alongside Suffocation and Pyrexia to create the 'NYDM' (New York Death Metal) sound.

This style integrated the rhythmic sensibilities of New York hardcore with the extremity of death metal. Their early demos, particularly 'Invocation of Evil,' laid the groundwork for the 'slam' aesthetic: chromatic, palm-muted riffing and vocal patterns that mirror the drum's syncopation. Despite numerous lineup changes and the tragic loss of founding drummer Bill Tolley in 2017, the band has remained a cornerstone of the underground. Their influence is visible in the modern 'slam' and 'brutal death' scenes, where their emphasis on the 'groove' remains a standard template for heavy songwriting.
