alien protein is a good choice, however, it might be not the best, it is better given if person liked IM and whos been fed for some while some other "cliche" stuff and wants for more, be it quality wise or simply seeks for something different or just simply asks you for another goa recommendation
as for cosmology, not sure if its good to be given to newcommer, even years into goa/psy listening i still dont dig that one too much, perhaps i should put it some day on play again
