Rick said it took 4 years to complete the album.
If we take in the fact Rick did the majority of his own production, plus the writing, filming the movie (which was shot across three different continents) then masterminding the marketing and promotion which includes the film premieres at various large scale film festivals; I think 4 years makes sense.
get what youre saying but its still 27 minutes of music to me, regardless of microwave era, personally feel its a bit too long putting the outcome in balance
