I did a traditional jazz (Dixieland?) gig this past week. I have a great 12x22 Slingerland bass drum that has calf heads on both sides. The drum always sounds great. I also have some additional calf heads so on a whim I decided to put calf on all of the drums. I have two nice heads on a Slingerland 16x16, a single headed Gretsch 8x12 and a Leedy Broadway standard that I put calf on the top and bottom. The set was totally outfitted with calf. I tried a similar experiment years ago on my usual gigging kit. It was very difficult especially in the extreme weather changes that Buffalo experiences. Heads would be super tight coming out of the car then get into the humidity in doors and drop into a tubby texture and tuning. For this gig I was careful to load the drums into the car last minute and then quickly transport to the performance area. The drums sounded fantastic. Even the snare with a bottom calf was responsive, rich and warm. I’m seriously thinking about revisiting this sound on my main gigging kit. I know there will be some trials and tribulations but the richness of the sound may be worth it. I’m addition to the rich overtones and naturally muted resonance the drums have a softer attack. You can really smack them and they don’t overpower. Of course the brush sounds are amazing. I just listenened to the Mel Lewis interview about Buddy Rich that was recently posted and he talks about his experiences with calf. I also remember years ago hearing the fantastic Joe LaBarbera, who was the main inspiration for my experiment years ago. Both of these drummers have an incredible sound. A couple of questions. I know that Kentville makes Kangaroo hide heads. Also Earthtone makes calf with a modern collar. How do these compare with traditional wood hoop calf heads? Are there other companies that sell traditional calf? What are your experiences with calf?
