Erik Grösch was already working with Ralf behind the scenes with the production, recording and engineering of Mekong Delta albums since ‘Visions Fugitives’. On ‘Wanderer on the Edge of Time’ he was introduced as one of the two new guitar players (Benedikt being the other). Since ‘Tales of a Future Past’ was recorded with only Peter Lake on guitar and he was also not involved with the production process, he is no longer considered to be an active part of the band.
