After almost three years of touring to promote "Metallica", including a headlining performance at Woodstock '94, Metallica returned to the studio to write and record its sixth studio album. The band went on a brief hiatus in the summer of 1995 and played a short tour, Escape from the Studio '95, comprising three outdoor shows, including a headline show at Donington Park supported by Slayer, Skid Row, Slash's Snakepit, Therapy?, and Corrosion of Conformity. The band spent about a year writing and recording new songs, resulting in the release of "Load" in 1996. "Load" debuted at number one on the "Billboard" 200 and ARIA Charts; it was the band's second number-one album. The cover art, "Blood and Semen III", was created by Andres Serrano, who pressed a mixture of his own semen and blood between sheets of plexiglass. The release marked another change in the band's musical direction and a new image; the bandmembers' hair was cut. Metallica headlined the alternative rock festival Lollapalooza festival in mid-1996.
