The Dell Music Center (formerly the Robin Hood Dell East) brings you the best in Rhythm & Blues, Gospel and Jazz entertainment. The Dell East concerts have their roots in free summer concerts sponsored by the City of Philadelphia at the Lemon Hill Concert Pavilion in Fairmount Park. Concerts were held near 31st and Poplar Streets, seven nights a week, during the summer in the 1920's. A 50 piece orchestra, composed mostly of members of the Philadelphia Orchestra, performed at the concerts, which attracted as many as 20,000 people. The crowds were too large to fit in the concert pavilion, and the overflow sat or stood on the grass around the pavilion, extending as far as the sounds of the orchestra could be heard.
