Springtime Again is from the album Sleeping Beauty  by  Sun Ra And His Arkestra.

This is the great late-night Sun-Ra chillout album you never knew about. The band had been working in a more groove-oriented setting off and on for over a year, as evidenced by the albums Lanquidity and On Jupiter, with both featuring prominent electric bass and electric guitar. Sleeping Beauty picks up right where On Jupiter left off, with the gentle, swaying “Springtime Again” echoing the same mellow vibe of “Seductive Fantasy” from On Jupiter. A skittering intro coalesces as different instruments pick up bits of the melody, which is then fully expressed by the horn section and ensemble vocals. It’s a simple two-chord vamp, with beautiful solos that seem to embody the reawakening and rebirth of springtime. There’s a good reason copies of this album go for several hundred dollars on the collector’s market, but it really deserves a proper release so more people can hear it. Outstanding. [source]
