When Tjader biographer S. Duncan Reid talked to Tjader's children about Verve reissues, they said they had inquired but the label wasn't interested. Only half of Tjader's Verve LPs were reissued on CD by the label, another two (In A Latin Bag & Saturday Night /Sunday Night At The Blackhawk) by Cherry Red in the UK. One only in Japan (The Prophet). Three (Warm Wave, Along Comes Cal, Hip Vibrations) never were on CD in complete form, only single tracks on compilations.
Tjader was positive about Warm Wave. He would have loved to record an all ballad LP with the rhythm section, but that never materialized. If the session tapes are still there they could release the album with and without the overdubs on one CD, that would be close to fulfilling Cal's dream.
That's a killer album! But I'm afraid the tapes are lost. There even is a film of this concert. Some snippets were on the McFarland documentary released a few years ago.
