However, the newfound sound proved too radical for co-founder and vocalist Derek Mc Kenzie, who left the band in late 1987 to study at university. Help was at hand in the charismatic form of Glaswegian Will Sinnott (23 December 1960 – ), aka Will Sin, who joined the group in October 1987, on bass and keyboards, freeing up Angus to handle vocals and guitar. He had already made an impression as part of the Can/SAHB influenced improvisation troupe Edith and the Ladies, and his father, a master wood craftsman, had made guitars for the Incredible String Band and John Martyn.At the start of 1988, the first music videos were shot for the Shamen, those being "Christopher Mayhew Says" and "Knature of a Girl".Released in June 1987, the Shamen's first album, Drop demonstrated their love of 1960s psychedelia, with influences such as Love, Syd Barrett and the 13th Floor Elevators.
But as I came to terms with it and thought about the situation I realised that what the Shamen was about was positivity and that positivity is like the spirit of the music and positivity acknowledges the need for change.
So for those reasons I elected to carry on and also I knew that the name Shamen really meant a lot to Will and that was one of the main attractions for joining the band for him." After finding a new female singer, Cheryl Melder, the Shamen embarked on the start of their Progeny tour. C now a full-time member of the Shamen, and Jhelisa Anderson (who was chosen to replace Plavka) providing guest vocals, the Boss Drum album followed in 1992.
Tensions had already begun to show, however - the band's barely concealed espousal of the then-fashionable new psychedelic drugs and the artistic pressures of altering direction from that of an acceptably skilled guitar band to an electronic dance act.
As they continued their Synergy tour, their popularity in the United Kingdom began to rapidly expand.
In May 1991, with the expansion of the popularity of their band, Will Sin decided to release an EP entitled "U Make Me Feel" with an unknown female singer under the pseudonym Elsi Curry, and it was released as a promotional record.
Later that same month, after the Sixth Mark of the Synergy Tour, and a one-week tour of Russia, the Shamen headed to Tenerife, to film a video for "Move Any Mountain".
Keith Mc Kenzie and Peter Stephenson were less impressed by these new developments, and left the group the following summer, after the January 1989 release of the In Gorbachev We Trust album, which saw the group further enhancing their sound. C and Evil Eddie Richards, who would later both work with the Shamen to help them transition their music into the rave scene.
Angus and Sinnott relocated to London, allowing them to start afresh, and plunge into the emerging rave scene.
The Shamen were preceded by Alone Again Or, the Love-inspired name under which they recorded their first psychedelic electronic pop singles.
After their name change, further singles picked up airplay from John Peel.
By September 1987, the Shamen were applying these techniques to their own music, mixing rock guitars, techno and hip-hop rhythms and sampled radio voices which was to prove so influential to groups like Jesus Jones and EMF.
