Always thought the title track went like mad on that one and was in a different class from the other tracks. Someone - Higgins, I think - is making a lot of "gone" noises on that one. Notice it had a different recording date from the others.
Thanks for reminding me aboout this one Bill and Bob. Disposed of the vinyl years ago but it's a fine session with Fathead being something of a BN wild card. The cds second session withe the three horn front line has some nice sounds too. Higgins is certainly 'gone' on Sonic Boom.
Looks like you've got the RVG edition, Bob. Mine's a Japanese import with only six tracks, all by the quintet, recorded 28 April 1967, except for "Sonic Boom" recorded April 14.
It's the King Japanese vinyl, Bill. I also have a 'Sonic Boom' Conn CD and a 'Rainbow series' LP so I'm well covered on this title.
I forgot to say mine's on CD. Apart from a 10-page booklet in Japanese, it includes what looks like a slightly scaled down copy of the back cover of the Liberty-reissued LP, with only a single line of Japanese and a number added.
