It’s been 32 years since Reverend Horton Heat, the band and the man, first pumped psychobilly through a sound system. There are relatively few disruptions in the musical lives of the Reverend and his bass-thumping sidekick Jimbo Wallace, but Arjuna “A.J.” Contreras has replaced longtime drummer Scott Churilla on this fall’s tour with Fishbone, Strung Out and Los Kung Fu Monkeys. And other than cutting back from an average of 200 to 120 shows a year, the Reverend Horton Heat marches on like it/he always has.

Contreras, who has played with Brave Combo and rockabilly artist Matt Hillyer, entered the studio with Wallace and the Reverend in August to record new material. The next release would be the first since the single “Hardscrabble Woman/Lying to Myself,” which was released for Record Store Day last year, but it remains to be seen whether there will be a full-length follow-up to 2014’s Rev or some sizzling singles to whet the appetites of the faithful. Regardless, fans can be assured that Contreras will be well seasoned by the time the psychobilly gospel is delivered in their hometown.
