I remember buying this as an L.P years ago. It was then (early 1970's) one of the very best Mahler discs around. But memory plays tricks, and would hearing it again on C.D. be as rewarding? You bet! It is a wonderful performance, where orchestra, conductor and engineers all came together to produce a classic. The L.S.O. is on superb form. The woodwind and brass sections in particular are special. Solti keeps the music moving, but is not as ruthless as he could be in some later Mahler recordings. The second movement Landler dances along, and the third, with its crazy clarinet interjections, is as bizarre as it should be. The finale is terrifically exciting, but relaxes where it should (wonderful string playing here).
The engineering is amazing for 1964; recorded in the Kingsway Hall, with John Culshaw producing, the sound is tangible in places, particularly the brass and percussion.
There are a number of fine Mahler 1's; but there are none better.
