1 small table for bows, brushes, sticks (Barry Guy)
Amplifier: one bass amp and 15" speaker (or combo) of very good quality e.g. Hartke or Gallien Krüger, SWP or Trace Elliott.
1 Jazz Drum kit (important: NOT rock & roll kit) for Paul Lytton
Snare drum and stand, 12" small tom tom, 14" large tom tom, 18" Bass Drum (with front head), 3 cymbal stands, hi-hat, drum stool, bass drum pedal. Drums must have Remo Ambassador Heads or similar NOT oil filled heads.
If the venue is supportive of acoustic music, the trio will only need amplification for the bass. Otherwise PA system with monitors for the three musicians plus microphone for Parker etc.
