Lebedev Concerto for Bass Tuba (on a Thein Ben Van Dijk Bass Trombone)

Here is a performance of Lebedev's Concerto for Bass Tuba on my Thein Ben Van Dijk bass trombone.
It's not perfect - I played this a minute after playing Sulek's Vox Gabrieli on me tenor trombone. So it goes.
Also, apologies for the mild audio breakup. I used the audio from my phone, and phone microphones aren't accustomed to bass trombones.
Thank you for listening!
