19 vinyl pressings of Piano Improvisations Vol. 1 are listed here, from 6 countries, released between 1971 and 2025.
The earliest pressings are from 1971, in Germany, Norway. One of them is ECM Records ECM 1014 ST.
Check the catalog number on the label (first-year pressings use ECM 1014 ST, SLP 1415) and the codes etched in the runout groove, then compare them with the pressings listed above; for example, ST-ECM 1.0.14-A¹ and ST-ECM 1014-B¹. Later reissues often keep the catalog number but change the label design or the runout codes.
It depends on which pressing you have and on the condition of the record and its sleeve. Early pressings from the album's home country in near mint condition are usually worth the most; common later reissues are worth far less. Scan your copy with VinylLens to see its value for every grade.
