the group. The following month Mecki Mark Men's residual five members went into Stockholm's Philips Studios to create their eponymous debut album. A tour of the U.K. and an appearance on the BBC television program Popside soon followed. By late 1967 the band had shrunk to the quartet of Bodemark, Nordstrom, Svanberg and Gartz for a tour of Finland with the Baby Grandmothers and Finnish singer Anki Lindqvist. In January 1968 Mecki Mark Men and Baby Grandmothers opened for the Jimi Hendrix Experience for the Swedish leg of Hendrix's European tour during a hiatus in the Electric Ladyland recording sessions. Jimi Hendrix had become acquainted with MMM on previous visits to Klubb Filips and he was regularly performing his own version of the Hansson and Karlsson tune "Tax Free." Hendrix played short sets on the tour due an injury from smashing a plate glass hotel window, but his forearm bandaged, he regularly jammed with the Mecki Mark Men when their bands were warming up for gigs. That year Mecki Mark Men also opened for Frank Zappa and the Mothers of Invention at Stockholm's Concert House. Because of Mecki Bodemark's Jimi-soundalike vocal style and his band's heavy, unpredictable and esoteric music, MMM often drew comparisons to both Hendrix and Zappa, even from those unaware of the artists' various associations. This iteration of Mecki Mark Men soon split up, with some members going on to found other Swedish bands. Gartz, who had been MMM's secondary songwriter, formed the quintet Pärson Sound, a project that originally came together to perform Terry Riley's composition, In C. Pärson Sound soon rebranded themselves as International Harvester, and then as Harvester, before settling on the name Träd, Gräs & Stenar ("Trees, Grass and Stones"), who became a staple of Swedish progg music in the early 1970s. Second lineup: late 1968–1971 1968 marked a big shift in Swedish youth culture as political protests erupted all over Europe. Demonstrations against the Vietnam War had started in Sweden the previous year, and future prime minister Olof Palme marched against it in his capacity as Minister of Education. Many Swedes were also involved in campaigns in support of the environment or against apartheid. On May 3 activists protested the participation of apartheid nations Rhodesia and South Africa in the international Swedish Open tennis competition held in the resort town of Båstad, resulting in a violent clash between Swedish police and demonstrators.
