There are at least five bands with the name 'Grapefruit': a psychedelic rock band band from London (1), a punk band from Hawaii (2), a czech crossover band (3) and an anarcho-folk/punk duo from England (4) a electronic project in Portland, Oregon (5).
These are photos from concerts where Grapefruit played, so they may be of other bands that played the concert as well.
