Nektar were an English band who were noticeably more successful in Europe than they were in the UK, particularly in Germany. They got together in Hamburg at the end of the 1960s apparently and worked and recorded in Germany, particularly on their earlier albums, which are pretty good examples of spacey prog. They continued to record and tour until the 1980s, I think and reformed in 2002, releasing a few albums and playing at prog festivals.
The band’s original line-up was;
Roye Albrighton – guitars, vocals
Allan Freeman – keyboards, backing vocals, mellotron
Ron Howden – drums, percussion, backing vocals
Derek Moore – bass, vocals
A Tab In The Ocean was their second release and it came out in 1972.
Here it is in all its progtastic glory;
