Van Van is sort of a special case in that they sometimes use gears and sometimes not. Here is Me mantengo for example. In Kevin's terminology the marcha gears are the ones used both in timba and salsa. I tried to set the timestamps after the video times not the album so you need to subtract about 14 seconds if you are listening to the CD plus I think they cut one section in the video.

• 00:15-00:55 charanga (note the use of the cha bell)
• 00:55-01:19 marcha abjao (cáscara, no bells, bass playing some kind of tumbao)
• 1:19-1:49 charanga
• 1:49-1:57 marcha abajo
• 2:12-2:24 charanga
• 2:24 coro 1 - marcha arriba (bells, bass playing some kind of tumbao)
• 3:05 puente - special section to transition
• 3:12 coro 2 - marcha arriba (bells, bass playing some kind of tumbao)
• 4:30 masacote gear - bass drops out piano and toms playing maybe congas too? (this is a timba gear because the bass drops out)
