The live record, "T-Square Live '90 (Featuring F-1 Grand Prix Theme)" is perfect in every way! I love the mic feedbacks, the echo of the room, the subdued ambience the audience sounds like they are in, the overfed drums, the big, big sound - "wrapped around your soul" makes me cry. They just tear it up and leave the stage singed and smoldering in their wake! I love everything about this record half to death! Beautiful fusion jazz from Japan.
The original recording of "Takarajima" was actually released on T-Square's (then, The Square) 1986 release-- S.P.O.R.T.S.--but a later iteration was on "T-Square Plays The Square"; that album includes T-Square covering their music from 1978 to 1988, when they were known as "The Square".
