Geoffrey James Nicholls (29 February 1944 – 28 January 2017)[2] was an English guitarist and keyboardist, and longtime member of the heavy metal band Black Sabbath until 2004.

Nicholls also played in the NWOBHM band Quartz before joining Black Sabbath.

Nicholls was originally brought in as a second guitarist when Black Sabbath doubted whether they would even continue under that name.

[4] Nicholls had performed on Martin's first two solo albums Back Where I Belong and Scream, and their support tours.

[5][6][7][8] "Geoff was a real true friend and supported me all the way for nearly forty years," said Tony Iommi.
