The Music Museum in Paris organizes every season concert tours. It proposes to musicians to sound the instruments of its collection; visitors can hear from one room to the other usually preserved behind glass instruments. On 11 November 2012, the Museum offers to Thomas Le Saulnier and Samuel Tailliez to participate to the concert walk “Ni vu, ni connu” playing the cello–Stroh and Stroh–violin. A big thank you to them !
