Steve Albini, the famed record producer and musician who worked with storied rock groups such as Pixies, Nirvana and others, has died at 61 of a heart attack, according to reports.

Studio staffers confirmed the rocker’s death to Pitchfork.

Albini is best known for producing Nirvana’s 1993 cult-classic album In Utero, in which he helped craft the record’s abrasive and metallic tones.

The Chicago-based icon also produced Foo Fighter’s “Something From Nothing” in 2014.

In addition to his studio production work, Albini was the guitarist and frontman for the group Shellac, who were set to release their first album in over a decade.

He also founded the often-confrontational punk group Big Black, among others.
