Portable Madness is the third triplet in the set Falsini and crew recorded in the early 70s. First was a self-titled promo-only set followed closely by Fragments of Light. All three were recorded in their studio on a farm near Florence, probably on the same Teac 4-track used to record and mix this album. All three were released in 1974. The records have similarities, being siblings from the same parent, but also display distinct personalities. This set is all instrumental where Fragments had a few vocal tracks. If you enjoyed Fragments you'll probably be happy with this one, as well.
