Limited 180gm flaming colored vinyl LP pressing. 50th anniversary edition. Released in 1973, Grinding Stone was Gary Moore's solo debut with The Gary Moore Band. The music on this album could be described as experimental, but on the album, Moore explores a number of styles, from the title track's instrumental "Boogie Rock" to soulful vocals on "Sail Across the Mountain" and 17 minutes of guitar and keyboard excursions on the surprisingly funky "Spirit".
