Experimental video, using micro cassette recorder with KROME's combi patch.
Although I have no skill to play real Jazz, I like this preset patch combi #B068 Jazz Record, it is simulating piano trio with LP record's sound (has scratch noise, narrow frequency range, etc) . But I thought it is still "Hi-Fi" then I used SONY M-201 micro cassette-corder to add real wow-flutter and narrow dynamic/frequency range to get much more older sound.
This technique causes A-V sync problem, so commercial tape recorder has no tape speed accuracy , I just synced at the beginning of this tune but unsynced very soon :D
What I'm playing here is arranged "Lum no Love Song" from Japanese classic slapstick manga/animation's tune.
