None of the plodding riffs, histrionic vocal stylings, or blues posturing that plagued many similar groups of this era mar this collection of melodic, tasteful progressive hard rock (as well as some mellower country-rock songs). Leader and main songwriter Gary Yoder would eventually join Blue Cheer and add his distinctive stamp to that band's sound. The 1999 Big Beat CD, titled Kak-ola, includes everything from the Kak LP, but also adds 11 bonus tracks. These include the 45 version of "Rain"; five previously unreleased acoustic cuts, four of them versions of songs from the LP, one ("Bye Bye/Easy Jack") of a tune that was not included on Kak; the "Flight from the East"/"Good Time Music" Gary Yoder solo single on Epic, released after Kak had split; and three Yoder solo demos from late 1967.
